Use a logarithm table or calculator to solve the log form.
X * log 8 = log 64 ; x = log 64/log8 ; x = 1.81/0.9 = 2.

$x = 2$ $x=2$

Use the fact that $64 = 8^{2}$ $64=8^2$ .

This gives us the equation:

$8^{x} = 8^{2}$ $8^x=8^2$

Since the bases are equal, we know their exponents must also be equal, giving the answer:

$x = 2$ $x=2$
