Introduction

When it comes to simplifying radicals, one of the most common operations is finding the square root of a fraction. This can be a bit tricky, but with the right approach, it can be a breeze. In this article, we will explore the concept of simplifying radicals, specifically the square root of a fraction, and provide a step-by-step guide on how to do it.

What is a Radical?

A radical is a mathematical expression that involves a root, such as a square root, cube root, or nth root. The most common type of radical is the square root, which is denoted by the symbol √. The square root of a number is a value that, when multiplied by itself, gives the original number.

Simplifying Radicals: A Step-by-Step Guide

Simplifying radicals involves finding the square root of a number or expression and simplifying it to its simplest form. To simplify a radical, we need to follow these steps:

Identify the Radical: The first step is to identify the radical in the expression. In this case, we have the square root of a fraction: √(6/100 + 16/100).
Simplify the Fraction: The next step is to simplify the fraction inside the radical. To do this, we need to find a common denominator for the two fractions. In this case, the common denominator is 100.
Add the Fractions: Once we have a common denominator, we can add the fractions together. In this case, we have: 6/100 + 16/100 = 22/100.
Simplify the Result: The final step is to simplify the result. In this case, we can simplify the fraction 22/100 by dividing both the numerator and the denominator by their greatest common divisor, which is 2.

Simplifying the Square Root of a Fraction

Now that we have simplified the fraction inside the radical, we can simplify the square root of the fraction. To do this, we need to find the square root of the numerator and the denominator separately.

Finding the Square Root of the Numerator

The numerator of the fraction is 22. To find the square root of 22, we can use a calculator or estimate it by finding two perfect squares that are close to 22. In this case, we can estimate that the square root of 22 is between 4 and 5.

Finding the Square Root of the Denominator

The denominator of the fraction is 100. To find the square root of 100, we can use a calculator or estimate it by finding two perfect squares that are close to 100. In this case, we can estimate that the square root of 100 is 10.

Simplifying the Result

Now that we have found the square root of the numerator and the denominator, we can simplify the result. In this case, we have: √(22/100) = √22/√100 = √22/10.
