So firstly, you want to get rid of the outermost powers. The rule with powering something with an exponent is to multiply the exponents together.


In this case:
(2x^(-2)y)^3=(2^(1*3)x^(-2*3)y^(1*3))=(8x^(-6)y^3) and
(4y^3)^2=(4^(1*2)y^(3*2))=(16y^6)


Our current equation look like this:
((-4x^2)(8x^(-6)y^3))/((16x^5)(16y^6))


Next, you want to multiply what's on the numerators and the denominator. The rule with multiplying exponents of the same base is to add them together.


In this case:
((-4x^2)(8x^(-6)y^3))/((16x^5)(16y^6))=(-32x^(2+(-6))y^3)/(256x^5y^6) =(-32x^(-4)y^3)/(256x^5y^6)



Now we can divide. The rule with dividing exponents with the same base is that you subtract them.


In this case:
(-32x^(-4)y^3)/(256x^5y^6)=-(1)/(8) x^(-4-5)y^(3-6)=-(1)/(8) x^(-9)y^(-3)


Now, if you're required to leave no negative exponents, the rule is that for example x^-2 would turn into 1/x^2. In this case, it would turn like this:
-(1)/(8x^9y^3) . And that would be your final answer.
