Question

What is the value of x when square root of x = 20

Answer 1

The value of x is 400.

Explanation:

sqrt(x)=20

(sqrt(x))^2=20^2

x=20^2

x=(20)(20)

x=400

Answer 2

Given data :

• 
  `√(x) = 20`

squaring both sides -

• 
  `( √(x) ) {}^(2) = (20) {}^(2)`

• 
  `x = 400`

value of x = 400
