<PRE><B>Question 62010</B>
pleae help me to simplify

{{{(3x^(-2))/(y^(-3))-2(x^4/y^6)^2}}}
{{{3y^3/x^2-2x^(4*2)/(y^(6*2))}}}
{{{3y^3/x^2-2x^8/y^12}}}  (Sometimes you can stop here)The LCD is x^2y^12
{{{y^12(3y^3)/(x^2y^12)-(x^2)(2x^8)/(x^2*y^12)}}}
{{{3y^(12+3)/(x^2y^12)-2x^(2+8)/(x^2*y^12)}}}
{{{3y^15/(x^2*y^12)-2x^10/(x^2*y^12)}}}
{{{(3y^15-2x^10)/(x^2*y^12)}}} (other times they want it to be written as a single fraction like this.)
Happy Calculating!!!</PRE>
