Question 76737
{{{(3*5)*(3*5/(3*5)+3*y*5*x*2*x*2*y/(3*5))}}}
{{{15*(3*5/15+3*5*y*y*x*x*2*2/15)}}}
{{{15*(3*5/(3*5)+3*5*y^(1+1)*x^(1+1)*2^(1+1)/15)}}}
{{{15*(3*5/15+3*5*y^2*x^2*2^2/15)}}}
{{{15*(3*5/(3*5)+3*5*2^2*y^2*x^2/15)}}}
{{{15*(3*5/15+3*5*2^2*y^2*x^2/(3*5))}}}
{{{15*(3*5/(3*5)+3*5*2^2*y^2*x^2/15)}}}
{{{15*(3*5/(3*5)+2^2*1*1*y^2*x^2/(1*1))}}}
{{{15*(3*5/15+2^2*y^2*x^2/1)}}}
{{{15*(3*5/(3*5)+2^2*y^2*x^2)}}}
{{{15*(3*5/15+4*y^2*x^2)}}}
{{{15*(3*5/(3*5)+4*y^2*x^2)}}}
{{{15*(1*1/(1*1)+4*y^2*x^2)}}}
{{{15*(1/1+4*y^2*x^2)}}}
{{{15*(1+4*y^2*x^2)}}}
{{{15*(4*y^2*x^2+1)}}} Answer

Good Luck!
