Question

Find the multiplicative inverse of $8^{-6}$.

• A. $6^8$
• B. $8^6$
• C. $6^{-8}$
• D. None

Answer 1

Answer: (B)

We have, $8^{-6}=8^6$
As we know that for any non-zero integer $a$, $a^{-m}=\frac{1}{a^m}$ where $m$ is a positive integer. $a^{-m}$ is the multiplicative inverse of $a^{\mathrm{m}}$.
