is $3^{3v}(3^{3w})= (3^4)^12$

$3^{3v+ 3w}= 3^{48}$.

$3v+ 3w= 48$ so $v+ w= 16$.

Yes, we have only one equation for v and w but the question does not ask us to solve for v and w.

The average of v, w, and 35 is $\frac{v+ w+ 35}{3}= \frac{16+ 35}{3}= \frac{51}{3}= 17$.

helps to write it out rather than quickly assume things
