Question 720995
{{{(3x^-2y^3)^2(2x^-6y^2)}}}
square everything inside the brackets (You multiply the exponents in this case)
{{{(9x^-4y^6)(2x^-6y^2)}}}
Combine, multiply like terms, (you add the exponents)
{{{18x^((-4-6))y^((6+2))}}} = {{{18x^-10y^8}}}
the reciprocal gets rid of the neg exponent
{{{(18y^8)/x^10}}}, the simplified equation with positive exponents
