Dari definisi bilangan berpangkat di atas, diperoleh beberapa sifat-sifat bilangan berpangkat yaitu:
am⋅an=am+n
contoh :
34⋅32 = 34+2
= 36
(-2)4 . (-2)5
= (-2)4+5
= (-2)9

Dari definisi bilangan berpangkat di atas, diperoleh beberapa sifat-sifat bilangan berpangkat yaitu:
am : an=am-n
contoh :
34 : 32 = 34-2
= 32
(-2)4 : (-2)5
= (-2)4-5
= (-2)-1
5
