Question

Which of the following is a step in simplifying the expression​

Answer 1

option B

Step-by-step explanation:

`\rightarrow \sf ((xy^2)/(x^(-3)y^3) )^(-4)`

multiply powers:
`\bold{(a^b)^c = a^(bc)}`

`\rightarrow \sf (x^(-4)y^(2*-4))/(x^(-3*-4)y^(3*-4))`

simplify the following

`\rightarrow \sf (x^(-4)y^(-8))/(x^(12)y^(-12))`
