Key Terms and Ideas in Power Play

These are the terms and ideas the exam asks about most. Learn each one so you can define it and use it in your answers.

Term / IdeaWhat it means
Basethe number being multiplied again and again, the 5 in 5 to the power 4
Exponenthow many times the base is multiplied, the 4 in 5 to the power 4
Exponential forma short way to write repeated multiplication, 2 times 2 times 2 is 2 cubed
Product rulen to power a times n to power b equals n to power a plus b
Power of a powern to power a, all raised to power b, equals n to power a times b
Quotient rulen to power a divided by n to power b equals n to power a minus b
Zero exponentany non-zero number to the power 0 equals 1
Negative exponentn to the power minus a equals 1 divided by n to the power a
Scientific notationa number written as a value between 1 and 10 times a power of 10
Remember: To multiply powers with the same base you add the exponents, and to divide them you subtract the exponents.
Watch Out: Adding is not the same as multiplying with exponents. 4 + 4 + 4 equals 3 times 4 which is 12, but 4 times 4 times 4 equals 4 cubed which is 64.
