Introduction

In mathematics, simplifying expressions is an essential skill that helps us to solve problems more efficiently and accurately. One of the common expressions that we come across in algebra and geometry is the square root of a number. In this article, we will focus on simplifying the expression $\frac{25}{\sqrt{50}}$ . We will break down the steps involved in simplifying this expression and provide a clear explanation of each step.

Understanding the Expression

The given expression is $\frac{25}{\sqrt{50}}$ . To simplify this expression, we need to understand the properties of square roots and how to manipulate them. The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16.

Simplifying the Expression

To simplify the expression $\frac{25}{\sqrt{50}}$ , we need to start by simplifying the square root of 50. We can do this by finding the prime factors of 50. The prime factors of 50 are 2, 5, and 5. We can write 50 as $2 \times 5 \times 5$ . Now, we can take the square root of 50 as $\sqrt{2 \times 5 \times 5}$ .

Using the Property of Square Roots

We know that the square root of a product is equal to the product of the square roots. Therefore, we can write $\sqrt{2 \times 5 \times 5}$ as $\sqrt{2} \times \sqrt{5} \times \sqrt{5}$ . This simplifies to $\sqrt{2} \times 5$ .

Simplifying the Expression Further

Now that we have simplified the square root of 50, we can substitute this value back into the original expression. We get $\frac{25}{\sqrt{50}} = \frac{25}{\sqrt{2} \times 5}$ . We can simplify this expression further by canceling out the common factor of 5 in the numerator and denominator.

Canceling Out Common Factors

We can cancel out the common factor of 5 in the numerator and denominator by dividing both the numerator and denominator by 5. This gives us $\frac{25}{\sqrt{2} \times 5} = \frac{5}{\sqrt{2}}$ .

Rationalizing the Denominator

To rationalize the denominator, we need to multiply both the numerator and denominator by the square root of 2. This gives us $\frac{5}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \frac{5\sqrt{2}}{2}$ .

Conclusion

In this article, we simplified the expression $\frac{25}{\sqrt{50}}$ by breaking down the steps involved in simplifying the square root of 50. We used the property of square roots to simplify the expression and then canceled out common factors to get the final answer. We also rationalized the denominator to get the final answer in the form of a fraction.

Final Answer

The final answer to the expression $\frac{25}{\sqrt{50}}$ is $\frac{5\sqrt{2}}{2}$ .
