We will delve into the concept of square roots, explain the process of finding square roots for fractions, and discuss the significance of this mathematical operation in various contexts.

What is the Square Root of 64/121?

The square root of 64/121, represented as √(64/121), simplifies to 8/11. This means that when you take the square root of the fraction 64/121, the result is 8/11.

Understanding Square Roots

Before we delve into √(64/121), let’s review the basics of square roots:

• Square Root: The square root of a number ‘x,’ denoted as √x, is a value that, when multiplied by itself, equals ‘x.’ In other words, (√x)^2 = x.
• Radical: The radical symbol (√) is used to represent the square root operation. It is placed in front of the number or expression for which we want to find the square root.

Finding the Square Root of a Fraction

When it comes to finding the square root of a fraction, such as 64/121, the process involves the following steps:

1. Express as a Fraction: Ensure that the number inside the radical is in fraction form. In this case, 64 is already in fraction form as 64/1, and 121 is in fraction form as 121/1.
2. Take the Square Root: Apply the square root operation to both the numerator and the denominator separately.√(64/121) = √(64/1) / √(121/1)
3. Calculate the Square Roots: Find the square roots of the numerator and denominator.√(64/121) = (√64) / (√121)
4. Simplify: Simplify the square roots of 64 and 121.√(64/121) = (8) / (11)

So, √(64/121) simplifies to 8/11.
