What is the value of any number or variable to the zero power

1, exception 0⁰ = 0

Step-by-step explanation:

Any number or variable ≠ 0 with an exponent of 0 equals 1

Why?  Look at the pattern below:

2³ = 8

2² = 8÷2 = 4

2¹ = 4÷2 = 2

2⁰ = 2÷2 = 1

2⁻¹ = 1/2

2⁻² = (1/2) ÷2 = 1/4

This pattern works for ALL numbers, except 0

0⁰ = 0

Explanation: Any number or variable taken to the zeroth power is equal to +1. The only exception to this rule is which is undefined.
