It's not just about finding the answer; it's about understanding the process and the underlying principles that make the solution possible.

Step 1: Simplifying the Expression for p

Our journey begins with simplifying the expression for p: p = (39 + √625) / 4. The key here is to recognize that √625 can be simplified. The square root of 625 is 25, since 25 * 25 = 625. Substituting this value, our equation transforms to p = (39 + 25) / 4. Now, we perform the addition within the parentheses: 39 + 25 equals 64. This simplifies the equation further to p = 64 / 4. Finally, we perform the division: 64 divided by 4 is 16. Therefore, we have successfully simplified the expression and found that p = 16. This initial simplification is crucial because it transforms the original complex expression into a simple, easily manageable value. By simplifying the expression for p first, we avoid dealing with square roots and fractions within square roots, which can be more complex and error-prone. This approach underscores the value of simplification as a fundamental strategy in mathematical problem-solving. It's a testament to the power of breaking down a problem into smaller, more manageable parts. Moreover, it showcases the significance of recognizing perfect squares and their square roots, a skill that frequently arises in mathematical calculations. The importance of meticulous attention to detail in each step of the simplification process must be emphasized to avoid making minor errors that might lead to a different result. By simplifying step-by-step, we can have full confidence in the accuracy of the intermediate and final results.

Step 2: Finding the Square Root of p

With p now simplified to 16, the next step is to determine the value of √p, which translates to finding the square root of 16. The square root of a number is a value that, when multiplied by itself, equals the original number. In this case, we are looking for a number that, when multiplied by itself, gives us 16. We know that 4 multiplied by 4 equals 16 (4 * 4 = 16). Therefore, the square root of 16 is 4. This means that √p = √16 = 4. This step highlights the fundamental concept of square roots and their relationship to squaring a number. It reinforces the idea that finding a square root is the inverse operation of squaring. Moreover, it demonstrates the importance of knowing perfect squares and their corresponding square roots, as this knowledge can significantly expedite problem-solving. The square root function is a cornerstone of mathematics, with applications spanning various fields, from geometry and physics to computer science and finance. Understanding how to calculate square roots, both manually and with the aid of calculators or software, is an essential skill for anyone working with numerical data or mathematical models. Furthermore, finding the square root often involves approximation methods, especially when dealing with non-perfect squares. While our current problem involves a perfect square, being aware of these approximation techniques broadens our problem-solving toolkit and allows us to tackle more complex scenarios. This step serves as a reminder of the interconnectedness of mathematical concepts, where basic operations like multiplication and division are intertwined with more advanced concepts like square roots and exponents.

Solution: √p = 4

After simplifying the expression for p and then calculating its square root, we arrive at the solution: √p = 4. This corresponds to option (b) in the original problem statement. The journey to this solution involved simplifying a numerical expression, recognizing a perfect square, and applying the definition of a square root. The key takeaway here is the systematic approach to problem-solving. By breaking down the problem into smaller, manageable steps, we were able to navigate the equation with clarity and arrive at the correct answer. This problem serves as a great example of how algebraic manipulation and a solid understanding of mathematical concepts can lead to efficient and accurate solutions. This highlights the significance of mastering fundamental mathematical skills, as they form the building blocks for tackling more complex problems. It's not just about memorizing formulas or procedures; it's about understanding the underlying principles and applying them strategically. Moreover, the problem demonstrates the importance of checking our work. While we arrived at a solution that matches one of the options, it's always a good practice to review our steps and ensure that our reasoning is sound and our calculations are accurate. This helps to minimize errors and build confidence in our problem-solving abilities. The process of finding the solution is a testament to the power of mathematical reasoning and the satisfaction that comes from successfully unraveling a mathematical puzzle.

Why is this Solution Correct?

To ensure the solution's validity, let's recap our steps. We began with p = (39 + √625) / 4. First, we simplified √625 to 25, giving us p = (39 + 25) / 4. Then, we added 39 and 25 to get 64, resulting in p = 64 / 4. Dividing 64 by 4, we found p = 16. Finally, we calculated the square root of 16, which is 4. Therefore, √p = √16 = 4. Each step was performed according to the order of operations and the properties of square roots. There were no approximations or estimations involved, ensuring the accuracy of the solution. This step-by-step verification underscores the importance of rigorous mathematical reasoning. It's not enough to simply arrive at an answer; we must also be able to justify why that answer is correct. This involves demonstrating a clear understanding of the underlying mathematical principles and showing how they were applied in each step of the solution process. Moreover, understanding why a solution is correct helps to solidify our understanding of the concepts involved. It allows us to connect the dots and see how different mathematical ideas fit together. This deeper understanding is invaluable for tackling more complex problems and for applying mathematical knowledge in real-world situations. Furthermore, the ability to explain and justify our solutions is a key skill in mathematics education and beyond. It's not just about getting the right answer; it's about communicating our reasoning effectively and demonstrating a solid grasp of the subject matter. By verifying our solution and explaining our reasoning, we reinforce our understanding and build our confidence as problem solvers.

Alternative Approaches to Solving the Problem

While we solved the problem by simplifying p first and then finding its square root, other approaches are possible. One alternative is to try to manipulate the original expression for p to fit the form of a squared expression. However, this approach might be more complex and time-consuming in this specific case. The method we used is the most straightforward and efficient way to solve this problem. Another alternative approach could involve the use of a calculator to evaluate the square root of 625 and perform the subsequent arithmetic operations. However, while calculators can be helpful tools, it's important to understand the underlying mathematical principles and be able to solve problems without relying solely on technology. This fosters a deeper understanding of the concepts and enhances problem-solving skills. Furthermore, some problems may not be easily solved using calculators, making it essential to have a strong foundation in mathematical techniques. Exploring alternative approaches can also be a valuable learning experience. It allows us to see how different methods can lead to the same solution, and it can help us develop a more flexible and adaptable approach to problem-solving. However, in the context of a timed exam or a situation where efficiency is crucial, choosing the most straightforward and efficient method is often the best strategy. Ultimately, the most effective approach to solving mathematical problems is to have a solid understanding of the fundamental concepts, practice various techniques, and develop the ability to choose the most appropriate method for each problem. This problem-solving agility is a valuable asset in mathematics and in many other fields.
