Question

Evaluate: $(4^{-1}\times 4^{-3})\times 4^3$

• A. $4$
• B. $1$
• C. $\frac{1}{4}$
• D. $-4$

Answer 1

The correct option is C $\frac{1}{4}$

$(4^{-1}\times 4^{-3})\times 4^3=\left(4^{-1-3}\right)\times 4^3$

$=4^{-4}\times 4^3$

$=4^{-4+3}$

$=4^{-1}$$=\frac{1}{4}$

So, option $C$ is correct.
