Question

use the zero-exponent rule to simplify the expression.
-7⁰
-7⁰ = \square (simplify your answer. type an integer or a fraction.)

Explanation:

Step1: Recall zero - exponent rule

The zero - exponent rule states that for any non - zero real number \(a\), \(a^{0}=1\). In the expression \(-7^{0}\), the base of the exponent is \(7\) (note that this is different from \((-7)^{0}\)).

Step2: Apply the zero - exponent rule

Using the zero - exponent rule, we know that \(7^{0} = 1\). Then, the expression \(-7^{0}\) is equal to \(-1\times7^{0}\). Substituting \(7^{0}=1\) into the expression, we get \(-1\times1=-1\).

Answer:

\(-1\)
