Tolong jwb penting dan ksh cra

1. a. 7³.7^5 .7^-3
(pangkatnya yang dihasil)
= 7^ 3+5-3
= 7^5
b. P^7. P^-1
= P^7-1
= P^6
c. 10. 10^6. 10^-4 .10^7
= 10^1+6-4+7
= 10^10
d. 1/5² . 1/5^-4 . 1/5^-4
= 1/5^2-4-4
= 1/5^-6
e. 5³.5^-1.5^5.5²
= 5^3-1+5+2
= 5^9

2. a. 2^10 : 2^8
= 2^10-8
= 2²
b. 3^8 . 3^-2
= 3^8-(-2)
= 3^10
c. 10 : 100^-2
= 10 : 0,01
= 1000
d. 3³ . 3^-1 : 3^5 . 3²
= 3^3-1-5+2
= 3^-1
e. 6^5 . 6² : 6³
= 6^5+2-3
= 6^4
