Question

evaluate ln 1/sqrt e^5

Answer 1

well start by rewriting it in index form

\[\frac{1}{\sqrt{e^5}} = {e^\frac{-5}{2}}\]

so you are looking at

\[\ln(e^{-\frac{5}{2}})\]

now you can simply use log laws for the base and exponent.

hope it helps

Answer 2

I don't know what index form is? I don't think we've gotten that far...

Answer 3

well indexs and powers... are the same thing...

but if you haven't gotten that far...

you can input the question straight into a calculator to get an answer

Answer 4
