Question

If x^1/2 = 8, what is the value of x?
a. 4
b. 8
c. 16
d. 64

Answer 1

(d) 64

Explanation:

Please write either x^(1/2) or x^0.5 or √x, to reduce the chances of misinterpreting your input.

√x = 8 becomes x = 64 when both sides are squared.

This corresponds to answer (d).

Answer 2

d. 64

Explanation:

x^1/2 = 8

Square each side

(x^1/2 )^2=( 8)^2

x = 64
