Question

1. evaluate: (4² − 5)⁰

Explanation:

Step1: Simplify the base

First, calculate the value inside the parentheses: \(4^2 = 16\), then \(16 - 5 = 11\). So the expression becomes \(11^0\).

Step2: Apply the zero - exponent rule

The zero - exponent rule states that for any non - zero number \(a\), \(a^0=1\). Since \(11
eq0\), \(11^0 = 1\).
