tolong di bantu secepatnya saya butuh bantuan kalian menyesaikan soal ini saya tidak faham

6) (48 ab^-2 c^3)/(4a^-2 b)^2 (3ab^3 c)^2
= (48 ab^-2 c^3) / (4^2 a^-4 b^2) (3^2 a^2 b^6 c^2)
= (48 ab^-2 c^3) / (16 . a^(-4 + 2) . b^(2 + 6) . 9 . c^2)
= (48 ab^-2 c^3) / (144 a^-2 b^8 c^2)
= (48/144) a^(1 - (-2)) b^(-2 - 8) c^(3 - 2)
= (1/3) a^3 b^-10 c^1
= (a^3 c) / (3b^10)

7) (3ab^-3 c)^2 (2abc)^3 / (18ab^-2 c)^-2
= (3^2 a^2 b^-6 c^2)(2^3 a^3 b^3 c^3) / (18^-2 a^-2 b^4 c^-2)
= (9 . a^(2 + 3) b^(-6 + 3) c^(2 + 3) . 8) / (18^-2 . a^-2 b^4 c^-2)
= 72 . a^5 . b^-3 . c^5 / (18^-2 a^-2 b^4 c^-2)
= 72 . (18)^2 . a^(5 - (-2)) b^(-3 - 4) c^(5 - (-2))
= 72 . 324 . a^7 b^-7 c^7
= 23328 a^7 c^7 / b^7

= 2^5 . 3^6 . a^7 c^7 / b^7
