Problem 10
Question
Evaluate each exponential expression. $$-9^{0}$$
Step-by-Step Solution
Verified Answer
The evaluated expression \(-9^{0}\) is 1.
1Step 1: Identify the base and the exponent.
In the expression \(-9^{0}\), -9 is the base and 0 is the exponent.
2Step 2: Apply the zero-exponent rule.
According to the zero-exponent rule, any non-zero base raised to the power of zero is 1. This rule applies to negative numbers as well, so \(-9^{0} = 1\).
