Jan 31, 2018

#### Answer:

You calculator should have two key, one marked, $\log$, and the or marked $\ln$
The $\log$ key is the base 10 logarithm ${\log}_{10} \left(x\right)$
The $\ln$ key is the base e logarithm ${\log}_{e} \left(x\right)$

#### Explanation:

Assuming that $\log 23$ means the base 10 logarithm, push the 2 key, push the 3 key, and then push the $\log$ key.
