Question 83966
{{{3xy^2(5xy-4x+6y)}}}
Use the distributive property and multiply through the 3xy^2. Note that when you 
multiply things with exponents, the rule is to keep the base and add the exponents. i.e. (x^2)(x^4)=x^6.
{{{highlight(15x^2y^3-12x^2y^2+18xy^3)}}}
Since you can't simplify any of the terms, you are done.
Good Luck,
