EXAMPLES

5. Big ideas Expression Property am · an = am+n (am)n = amn (ab)m = ambm
Product of powers property
(am)n = amn
Power of a power property
(ab)m = ambm
Power of a product property
am/an = am-n a = 0
Quotient of powers property
(a/b)m = am/bm b = 0
Power of a quotient property

6. Define and use zero and negative exponents
Words
Algebra
Example
a to the zero power is one
a0 = 1 a=0
50 = 1
a-n is the reciprocal of an
a-n = 1/a a=0
2-1 = ½
an is the reciprocal of a-n
an = 1/a-n, a=0
2 = 1/2-1
