Formula Explained

The square root of a fraction is calculated using the following formula:

Square Root of a Fraction Formula

√(a/b) = √a / √b

Where:

  • a is the numerator of the fraction
  • b is the denominator of the fraction

This formula allows you to find the square root of a fraction by taking the square root of the numerator and the denominator separately, then dividing them.

Worked Examples

Example 1: Simple Fraction

Find the square root of 9/16.

Using the formula:

√(9/16) = √9 / √16 = 3/4

The square root of 9/16 is 3/4.

Example 2: Complex Fraction

Find the square root of 18/8.

First, simplify the fraction:

18/8 = 9/4

Now apply the square root formula:

√(9/4) = √9 / √4 = 3/2

The square root of 18/8 is 3/2.

Example 3: Fraction with Radicals

Find the square root of 2/8.

First, simplify the fraction:

2/8 = 1/4

Now apply the square root formula:

√(1/4) = √1 / √4 = 1/2

The square root of 2/8 is 1/2.

Frequently Asked Questions

Can I find the square root of a negative fraction?

No, the square root of a negative fraction is not a real number. It results in an imaginary number, which is beyond the scope of this calculator.

How do I simplify the square root of a fraction?

First, simplify the fraction to its lowest terms, then apply the square root formula to the numerator and denominator separately.

What if the numerator or denominator is not a perfect square?

The calculator will display the result in radical form, which is the simplest exact form. For decimal approximations, it will provide a rounded value.
