Answer:

x can be replaced by 8 and -8

Step-by-step explanation:

Given : 1: x = x:64

We have to find the value of x,

Consider 1: x = x:64

This is same as writing,

\frac{1}{x}=\frac{x}{64}

\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c

64=x^2

Taking square root both sides, we have,

x=\sqrt{64}

We know \sqrt{64}=\pm 8

x=\pm 8

Thus, x has two values x = 8 and x = -8
