### Find the positive value of x such that log (x) 64 = 2

Find the positive value of x such that logx64 = 2

Using the logarithm rules, we know that we can rearrange the given equation into the form:

x2 = 64

Knowing this, we square root both sides to get

x = 8, x= -8

As the value of x must be positive, the solution must be

x = 8
