QuestionWhich expression equals $4^{5} \times 4^{-7} \div 4^{-2}$? Options: 1) $\frac{4^{5} \cdot 4^{-2}}{4^{-7}}$ 2) $4^{-4}$ 3) $4^{5} \div 4^{-9}$ 4) $4^{0}$

Studdy Solution
Finally, according to the zero exponent rule, any non-zero number raised to the power of0 is1. So, $4^{0}$ equals1.
The expression $4^{5} \times4^{-} \div4^{-2}$ is equal to $4^{0}$, which equals1.
