Is it like 1/3 or something? Because 2^3 = 8...

ask yourself what power you would raise the number 8 to in order to get 2
i.e. solve \(8^x=2\) for \(x\)

yes, it is \(\frac{1}{3}\) because
\[8^{\frac{1}{3}}=\sqrt[3]{8}=2\]

use the property of logarithm:
\(\huge log_ba=\frac{log a}{log b}\)
yup its 1/3.
