Question

Tolong dibantu ya besok dikumpulin nih
1. 21p4 q5 r3 ∶ (8p2 qr3 ∶ 2pqr)
2. p4 q6 r5 ∶ pq2 r2
3. 18a3 b5 c6 : 2 ab2 ∶ 3 a2 c2



tolong banget dgn caranya

Answer 1

2. p^4 q^6 r^5 / p q^2 r^2 = p^(4-1) q^(6-2) r^(5-2) = p^3 q^4 r^3\

3 18 a^3 b^5 c^6 / 2 a b^2 = 9 a^(3-1) b^(5-2) c^(6-0) = 9a^2 b^3 c^6

=  9a^2 b^3 c^6 / 3a^2 c^2 = 3 a^(2-2) b^(3-0) c^(6-2) = 3b^3c^4

* a^0 = 1

ngga tau sih benar atau salah
