Tentukan hasil dari: a) 8 a^6 b^2 / 2 a^3 b^2 b) (4 a^2

a) 4a^3, b) 16a^4b^5

Pembahasan

a) 8 a^6 b^2 / 2 a^3 b^2 = (8/2) * (a^6 / a^3) * (b^2 / b^2) = 4 * a^(6-3) * b^(2-2) = 4 * a^3 * b^0 = 4a^3
b) (4 a^2 b^3)^3 / (2 a b^2)^2 = (4^3 * (a^2)^3 * (b^3)^3) / (2^2 * a^2 * (b^2)^2) = (64 * a^6 * b^9) / (4 * a^2 * b^4) = (64/4) * (a^6 / a^2) * (b^9 / b^4) = 16 * a^(6-2) * b^(9-4) = 16a^4b^5
