a counter example.

If $f(n)$ is $(g(n)),$ then $3^{f(n)}$ is $(3^{g(n)}).$

$f(n)+g(n)$ is $.$Question V $(10$ points$)$: Determine whether the following statements are true or false. If true, prove your answer.

If false, provide a counter example.

If $f(n)$ is $(g(n)),$ then $3^{f(n)}$ is $(3^{g(n)}).$

$f(n)+g(n)$ is $.$

$2^{na}$ is $O(2^n),$ where $a$ is a constant.
