tolong ya semua nya,pakai cara ya plisss,kalau bisa:( bsk dikumpul

1.
a) 5^3 x 5^4
=5^(3+4)
=5^7
=...

b) (-3)^5 x (-3)^2
=(-3)^(5+2)
=(-3)^7
=...

c) a^4 x a^3
=a^(4+3)
=a^7


2.
a) 5^7/5^3
=5^(7-3)
=5^4
=...

b) (-7)^6/(-7)^4
=(-7)^(6-4)
=(-7)^2
=...

c) a^5/a^3
=a^(5-3)
=a^2

3.
a) (4^2)^3
=4^(2 x 3)
=4^6
=...

b) ((2/3)^3)^5
=(2/3)^(3 x 5)
=(2/3)^15
=...

c) ((a/b)^2)^3
=(a/b)^(2x3)
=(a/b)^6

hasilnya itung sendiri yaa hehe
