I was wondering if you guys could help. The two problems I cant get are:

1) [tex] xy{\sqrt{125x^3y^5}} - {\sqrt{12x^5y^7}} + x^2y^3{\sqrt{{80xy}} [/tex]

2) [tex] {\sqrt[3]{16x^4y^3}} - 5x{\sqrt[3]{54xy^3}}} + 20y{\sqrt[3]{2x^4}} [/tex]

It seems so easy, jjust adding and subtracting, but I don't remember how to do this type of stuff.

Thanks in advance guys.
