b) ( 3^5 : 3^2) . ( 3^10 . 3^5)
c) ( 10^4 .10^2 .10) . ( 10^10 : 10^4 : 10^2)
d) ( 5^15 : 5^5 : 5) . ( 5^10 : 5^5)

Answer 1

A) (2^2 × 2^4) ÷ (2^8:2^5)
2^6÷2^3
2^3

B) (3^5:3^2) . (3^10.3^5)
3^3 . 3^15
3^18

C) (10^4.10^2.10^1) . (10^10 :10^4 :10^2)
10^7 . (10^10:10^4 . 10^0:10^2)
10^7 . (10^6 . 10^-2)
10^7 . 10^4
10^11

D) (5^15:5^5 . 5^0 :5^1) . (5^5)
(5^10 . 5^-1) . (5^5)
5^9 . 5^5
5^14
