A negative exponent means the power moves to the reciprocal side of a fraction. The exponent becomes positive after the move. This rule requires a nonzero base because division by zero is undefined.
⚠Note: If the base is 0 and the exponent is negative, the expression is undefined.
How Negative Exponents Work
Identify the negative exponent, move the power across the fraction bar, then write the exponent as positive.
Reciprocal
Negative powers move to the opposite side of a fraction.
