Question

How do you solve 64x^2=1

The picture is what I did before-which was wrong.

Answer 1

x = ± 1/8

Explanation:

64 x^2 =1

Divide each side by 64

64 x^2/64 = 1/64

x^2 = 1/64

Take the square root of each side, remembering to take the positive and negative.

sqrt(x^2) = ±sqrt(1/64)

x = ±sqrt(1)/ sqrt(64)

x = ± 1/8
