Power of a Quotient
(a/b)^m= (a^m)/(b^m)
Product of Powers
when multiplying like bases add the exponents ( a^2 )(a^3) = a^5
Power of a Power
when raising a power to a power multiply exponents (a^2)^3= a^6
n is even integer 1. a<0 2. a=0 3. a>0
1. no real nth roots 2. one real nth root: 3. two real nth roots:
n is odd integer 1. a<0 2. a=0 3. a>0
1. one real nth root: 2. one real nth root: 3. one real nth root:
Negative Exponents
Raising a number to a negative exponent is the same as raising the number's reciprocal to the equivalent positive exponent. {a^-2 = 1/a^2} {1/a^-2 = a^2}
radical exponent notation
a^m/n= (a^1/n)^m= ()^m
Quotient of Powers
for all integers m and n and any nonzero number a, a^m/ a^n = a^m - ^n
Power of a Product
for all numbers a and b, and any integer m, (ab)^m = a^m X b^m
Zero Exponent
for any nonzero number a, a^0 =1
