tolong yang jago matematika nomer 1 dan 2

1)
[(32 a^5)/(243 b^5)] × [(2 b^2)/(a^3)]
= (64 a^5 b^2)/(243 a^3 b^5)
= (64 a^2)/(243 b^3)

2)
[((2 x^10)/(3 y^4)) × ((y^2)/(x^6))] × [(3 x^2)/(y^5)]
= [(2 x^10 y^2)/(3 y^4 x^6)] × [(3 x^2)/(y^5)]
= [(2 x^4)/(3 y^2)] × [(3 x^2)/(y^5)]
= (6 x^6)/(3 y^7)
= (2 x^6)/(y^7)
