Question

how can you write the expression as a single power of 4?
$\frac{1}{4^5} = \frac{4^0}{4^5}$
$= ?$
$4^{0+5}$
$4^{0-5}$
$4^{0 cdot 5}$
$4^{0 div 5}$

Explanation:

Step1: Recall exponent division rule

For same bases, $\frac{a^m}{a^n}=a^{m-n}$

Step2: Apply rule to given expression

Here $a=4$, $m=0$, $n=5$, so $\frac{4^0}{4^5}=4^{0-5}$

Answer:

$4^{0-5}$
