What is the power of a negative number?

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.

What is the rule for squaring negative numbers?

Squaring Removes Any Negative We started with minus 3 and ended with plus 3. When we square a number, then take the square root, we may not end up with the number we started with! That also happens for all even (but not odd) Exponents.
