Question 1034210
{{{((4x^-3y^2)/(xy^-5))^-2}}}
Combine like term exponent in a manner that will yield positive exponents only
{{{((4y^((2+5)))/(x^((1+3))))^-2}}} = {{{((4y^7)/x^4)^-2}}}
Get rid of the negative exponent, invert the fraction
Square 4 and multiply the exponents by 2
{{{(x^4/(4y^7))^2}}} = {{{x^8/(16y^14)}}}
