First one to answer the CORRECT one gets a brainliest :P

Answer 1

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Solution~~}}}}$

$= > 3 {}^{2} \times 3 {}^{x} = 3 {}^{7} \\ = > 3 {}^{2 + x} = 3 {}^{7} \\ = > 2 + x = 7 \\ = > x = 7 - 2 = 5$

Answer 2

3² × 3^x = 3^7

we know that,

a^m × a^n = a^(m+n)

So, by following this,

2 + x = 7

x = 5.
