Question

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

Answer 1

Given data :

• $\sqrt{x} = 20$

squaring both sides -

• $( \sqrt{x} ) {}^{2} = (20) {}^{2}$

• $x = 400$

value of x = 400

Answer 2

Answer:

The value of x is 400.

Step-by-step explanation:

sqrt(x)=20

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

x=20^2

x=(20)(20)

x=400
