Answer

False Explanation 1. Analyze (-x)^y (-x)^y means raising the entire expression -x to the power of y. If y is even, (-x)^y = x^y. If y is odd, (-x)^y = -x^y. 2. Analyze -x^y -x^y means applying the negative sign after raising x to the power of y. It is always -(x^y) regardless of whether y is even or odd.

Explanation

1. Analyze $(-x)^y$<br /> $(-x)^y$ means raising the entire expression $-x$ to the power of $y$. If $y$ is even, $(-x)^y = x^y$. If $y$ is odd, $(-x)^y = -x^y$.<br />2. Analyze $-x^y$<br /> $-x^y$ means applying the negative sign after raising $x$ to the power of $y$. It is always $-(x^y)$ regardless of whether $y$ is even or odd.
