Exponents and Powers
Laws of Exponents
If a, b are non-zero integers and m, n are any integers, then
Powers With Negative Exponents
If a is any non-zero integer and m is a positive integer, then
a-m =1/am
Note: a-m is called the multiplicative inverse of am as a-m × am = 1.
It is obvious that am and a-m are multiplicative inverses of each other.
