Transcript text: Simplify. Assume z $\neq 0$.
\[
\left(z^{-6}\right)^{7}
\]
Solution
Solution Steps
To simplify the expression \((z^{-6})^{7}\), we can use the power of a power property of exponents, which states that \((a^m)^n = a^{m \cdot n}\). Applying this property, we multiply the exponents \(-6\) and \(7\).
Step 1: Apply the Power of a Power Property
To simplify the expression \((z^{-6})^{7}\), we use the power of a power property of exponents, which states that \((a^m)^n = a^{m \cdot n}\). Here, \(a = z\), \(m = -6\), and \(n = 7\).
Step 2: Multiply the Exponents
Multiply the exponents \(-6\) and \(7\) to find the new exponent for \(z\):
\[
-6 \times 7 = -42
\]
