#### Answer

Answer:
256

#### Work Step by Step

Given:
$\frac{4^{7}}{4^{3}}$
The general formula is:
$\frac{x^{m}}{x^{n}}$ = $x^{m - n}$
We make the following substitutions into the general formula:
x = 4,
m = 7, and
n= 3.
Thus,
$x^{m - n}$ = $4^{7 - 3}$ = $4^{4}$.
$4^{4}$ = 4 $\times$ 4 $\times$ 4 $\times$ 4 = 16 $\times$ 16 = 256.
