Use the zero and negative exponent rules to simplify each expression. \((-9)^{0}\)

Short Answer

Expert verified
The simplified expression for \((-9)^{0}\) is 1.

Step by step solution

01

Recognizing the exponent rule

The problem is to simplify \((-9)^{0}\). From the rules of exponents, it is recalled that any number \(a\) (where \(a ≠ 0\)) to the power of zero equals 1, i.e., \(a^{0} = 1\).
02

Applying the zero exponent rule

Applying this rule to \((-9)^{0}\) gives \(1\) since \((-9)\) is a non-zero number.
