# What is log_8(5*8)?

Jul 6, 2018

$\approx 1.77$

#### Explanation:

We can simplify the parenthesis to now get

${\log}_{8} \left(40\right)$

Since we have no perfect squares or cubes and we're not dealing with base-$10$ or base-$e$, it would be best to evaluate this with a calculator.

${\log}_{8} \left(40\right) \approx 1.77$

Hope this helps!
