Question 978238
<pre>
First you have to know how to get this:

{{{(A+B)^6}}}{{{""=""}}}{{{A^6+6A^5B+15A^4B^2+20A^3B^3+15A^2B^4+6AB^5+B^6}}}

Do you know how?  If not ask how in the thank-you note form below.

Then substitute {{{A = (x^3)}}} and {{{B=(y^2)}}}

{{{( (x^3)^""+(y^2)^"" )^6}}}{{{""=""}}}{{{(x^3)^6+6(x^3)^5(y^2)+15(x^3)^4(y^2)^2+20(x^3)^3(y^2)^3+15(x^3)^2(y^2)^4+6(x^3)(y^2)^5+(y^2)^6}}}

Simplify:

{{{(x^3+y^2)^6}}}{{{""=""}}}{{{x^18+6x^15y^2+15x^12y^4+20x^9y^6+15x^6y^8+6x^3y^10+y^12}}}
