The concept of a "Zero Exponent" refers to the rule in mathematics that states any non-zero number raised to the power of zero equals one. For example, 2^0 or 5^0 both equal 1. This rule applies to all real numbers except for zero itself, as 0^0 is considered indeterminate. This rule can be understood through the properties of exponents. When dividing like bases, such as a^m divided by a^m, the result is a^(m-m), which simplifies to a^0. Since any number divided by itself equals one, this reinforces the idea that any non-zero number raised to the zero exponent is one.
