Problem 8
Question
Evaluate each exponential expression. $$(-9)^{0}$$
Step-by-Step Solution
Verified Answer
The evaluation of \((-9)^{0}\) equals 1.
1Step 1: Identify the base and the exponent
In this expression, the base is -9, and the exponent is 0.
2Step 2: Apply the zero exponent rule
Since the exponent is 0, any number (except 0) raised to the power 0 is always equal to 1. Hence, \((-9)^{0}\) equals 1.
