Answer 1

If 3 = $m^x$, then we know 9 = $(m^x)^2$ because 9 is 3 squared.

$(m^x)^2$ can be simplified to $m^{2x}$

So now we know $9m^2$ = $m^{2x}$·$m^2$

Since $m^{2x}$ and $m^2$ have the same base, we can express it as a single term by adding the exponents together.

So the answer is C) $m^{2x+2}$
