For powers with the same nonzero base, dividing means subtracting the exponents: , because common factors in the numerator and denominator cancel; when exponents are equal, the quotient is . This applies to numerical and simple algebraic expressions with whole-number exponents and supports simplifying scientific notation; exponents are not divided. Cases resulting in negative exponents or requiring more advanced exponent laws are outside this level.
When you divide powers with the same nonzero base, keep the base and subtract the exponents:
This works because matching factors cancel.
Example:
Step 1: Subtract the exponents.
Step 2: Simplify the exponent.
Step 3: Evaluate if needed.
So,
Remember: subtract the exponents; do not divide them. If the exponents are equal, the quotient is , because all the matching factors cancel.
