Exponent Rules
Exponent 0
a0 = 1
50 = 1
Exponent 1
a1 = a
51 = 5
Negative Exponent
Fractional or Rational Exponent
Negative Fractional Exponent
Product Rule
am · a n = am+n
25 · 22 = 25+2 = 27
Quotient Rule
am : a n = am - n
25 : 22 = 25 - 2 = 23
Power Rule
(am)n=am · n
(25)3 = 215
Same Exponent
an · b n = (a · b) n
23 · 43 = 83
an : b n = (a : b) n
63 : 33 = 23
