Difficulty: Easy
Correct Answer: 1
Explanation:
Introduction / Context:
The zero-exponent rule states that for any nonzero real number a, a^0 = 1. This is consistent with the laws of exponents and ensures continuity of exponent rules across integers.
Given Data / Assumptions:
Concept / Approach:
Use a^m / a^m = a^(m−m) = a^0 = 1 for any nonzero a. Therefore (100)^0 = 1.
Step-by-Step Solution:
Verification / Alternative check:
Consider 100^n / 100^n = 1. The left equals 100^(n−n) = 100^0; so 100^0 must be 1.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing 0^0 (indeterminate in some contexts) with a^0 for a ≠ 0. Here the base is nonzero.
