ANSWER

C. x=7

EXPLANATION

The given exponential equation is

${3}^{x - 5} = 9$

We rewrite the right hand side as 3 raised to exponent 2.

${3}^{x - 5} = {3}^{2}$

Observe that the base of both sides of the equation are equal.

We now equate the exponents.

$x - 5 = 2$

Solve for x,

$x = 2 + 5$

$x = 7$

The correct choice is C.
