Question

Which of the following is a step in simplifying the expression x multiplied by y to the power of 3 over x to the power of negative 4 multiplied by y to the power of 4, the whole to the power of negative 2.

Answer 1

((x)(y^3)/(x^-4)(y^4))^-2
((y^4)(x^-4)/(x)(y^3))^2
(y^4)/(x^4)(x)(y^3))^2
((y^4)/(x^5)(y^3))^2
((y^(4-3))/(x^5))^2
(y/x^5)^2
(y^2)/(x^10)
