Sifat-Sifat Bilangan Berpangkat
Sifat pertama:
52.53 =(5.5).(5.5.5)
=(5.5.5.5.5)
=55
a4.a2=(a.a.a.a).(a.a)
=(a.a.a.a.a.a)
=a6

Sifat-Sifat Bilangan Berpangkat
Kesimpulan:
am.an=(a.a.a...a).(a.a.a...a)
=(a.a.a...a.a.a.a...a)
=am+n
4
Multiple Choice
Sedehanakan bilangan berpangkat x3.x5 adalah...
x15
x8
x−8
x−15
5
Pembahasan
x3.x5 =(x.x.x).(x.x.x.x.x)
=(x.x.x.x.x.x.x.x)
=x8
atau x3.x5 =x3+5
=x8

a42
a12
a5
a10
7
Pembahasan
a7.a3.a2=(a.a.a.a.a.a.a).(a.a.a).(a.a)
=(a.a.a.a.a.a.a.a.a.a.a.a)
=a12
atau a7.a3.a2 =a7+3+2
=a12
