Select all the expressions that are equivalent to (3^-5)^-1. Multi-select Choices: (A)1/3^5 (B)3^-6 (C)1/3^-6 (D)3^5

Exponent Rule Explanation: Understand the exponent rule for powers raised to powers. When we have an expression of the form (a^b)^c, we multiply the exponents b and c. (3^-5)^-1 = 3^(-5 * -1) = 3^5Simplify the Expression: Compare the result from Step 1 with the given choices. We found that (3^-5)^-1 simplifies to 3^5. Now we need to determine which of the given choices are equivalent to 3^5. (A) 1/3^5 is the reciprocal of 3^5, so it is not equivalent. (B) 3^-6 is 3 raised to the negative sixth power, which is not the same as 3^5. (C) 1/3^-6 is the reciprocal of 3^-6, which simplifies to 3^6, not 3^5. (D) 3^5 is exactly what we found in Step 1, so it is equivalent.

Exponent Rule Explanation: Understand the exponent rule for powers raised to powers. $\newline$ When we have an expression of the form $(a^b)^c$ , we multiply the exponents $b$ and $c$ . $\newline$ $(3^{-5})^{-1} = 3^{(-5 \times -1)} = 3^5$
Simplify the Expression: Compare the result from Step $1$ with the given choices. $\newline$ We found that $(3^{-5})^{-1}$ simplifies to $3^5$ . Now we need to determine which of the given choices are equivalent to $3^5$ . $\newline$ (A) $\frac{1}{3^5}$ is the reciprocal of $3^5$ , so it is not equivalent. $\newline$ (B) $3^{-6}$ is $3$ raised to the negative sixth power, which is not the same as $3^5$ . $\newline$ (C) $\frac{1}{3^{-6}}$ is the reciprocal of $3^{-6}$ , which simplifies to $3^5$ $0$ , not $3^5$ . $\newline$ (D) $3^5$ is exactly what we found in Step $1$ , so it is equivalent.
