Any nonzero number raised to the 0 power equals which value?

Explanation:
When you see a base raised to the power of zero, the rule is that you’re multiplying the base by itself zero times. That means you’re left with the multiplicative identity, which is 1. A quick way to see why: for any nonzero base a, the expression a^m / a^m equals 1, but also a^m / a^m equals a^{m-m} = a^0. Since a^m / a^m is 1, it follows that a^0 must be 1. This makes the exponent rule consistent for any nonzero base, so a^0 = 1. Examples: 5^0 = 1, (-3)^0 = 1. The result doesn’t apply to zero as the base in this statement, since 0^0 is a special case and is treated differently in many contexts.
