Question

Im so confused please help me :((

Answer 1

`A) \sf \ \sf (x^8)/(16y^4)`

Step-by-step explanation:

`\sf \left((2y)/(x^2)\right)^(-4)`

inverse of the expression

`\sf \left((x^2)/(2y)\right)^(4)`

distribute power inside parenthesis

`\sf \left(((x^2)^4)/((2y)^4)\right)`

apply exponent rules:
`\s(a^b )^c = a^(bc)`

`\sf (x^8)/(16y^4)`
