What is the value of c in the equation below?

Rudik [331]

Answer:

D

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ and $a^{-m}$ = $\frac{1}{a^{m} }$

Given

$2^{-4}$ × 2² = $2^{(-4+2)}$ = $2^{-2}$ = c , hence

c = $2^{-2}$ = $\frac{1}{2^{2} }$ = $\frac{1}{4}$ → D
