# Math Help - Logarithms in Exponents

1. ## Logarithms in Exponents

Okay I'm having a small issue with logarithms. I have this problem assigned by my teacher: . How precisely do I solve this problem? And moreover what is the general rule to solving other problems like this?

Hint: $\log_2 2^4 = 4\log_2 2$

3. Hello there,

well i hope you know that you can simplify the exponential:
$e^{log_2 16}
= e^{log_2 2^4}
= e^{4log_2 2}
= e^4$

4. Thanks, that helped a lot.

5. actually you cannot solve the problem since there is no variable for which to solve

it seems to simplify to e^4 + 2

agreement?
