Describe an easy way to find the square root<br> when the number is not a perfect square?

marissa [1.9K]

The product of a rational number multiplied by itself is called as a perfect square.,we can easily find out the square root for a number which is a imperfect square

Step-by-step explanation:

using the following formula we can find a square root for a number which is a imperfect square

X = Non perfect square

√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )

$√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )$ Example
