Ingat sifat bilangan berpangkat berikut.

a to the power of m times a to the power of n equals a to the power of m plus n end exponent

open parentheses a to the power of m close parentheses to the power of n equals a to the power of m n end exponent

open parentheses a b close parentheses to the power of m equals a to the power of m b to the power of m

a to the power of negative m end exponent equals 1 over a to the power of m comma space a not equal to 0
