Question

Tlg dong yg bisa mtk poinnya 20
kerjain no 3b sm 5b pake jalan

Answer 1

3b. 2a√a^3b^5 + 3ab√a^5b^7
= 2a.a^3/2.b^5/2 + 3ab. a^5/2.b^7/2
= 2.a.a^3/2.b^5/2 + 3.a.b.a^5/2.b^7/2
= 2.(a.a^3/2).b^5/2 + 3.(a.a^5/2).(b.b^7/2)
= 2.(a^(1+3/2)).b^5/2 + 3.(a^(1+5/2)).(b^(1+7/2))
= 2.a^5/2.b.5/2 + 3.a^7/2.b^9/2
= 2√a^5√b^5 + 3√a^7√b^9
= 2√a^5b^5 + 3√a^7b^9
