Exponent Rules OR Exponents Rule!
Laws of exponents for real numbers a and b and integers m and n:
am an = am + n
52 5 4 = 56
= am n
a n =
a0 = 1
10 0 = 1
a b n
a = a
a 10 b ,
where 1 a < 10 and b is an integer
Simplify. All final answers should have positive exponents only. Use the
exponent rules, and then you are welcomed to confirm your answers with a
