Question

Anyone know the answer?

Answer 1

x^7/y^3

Explanation:

x^3+y^2+x^4+y^-5

re-arrange

x^4+x^3+y^-5+y^2

x^4+3+y^2-5

x^7+y^-3

let the minus(-)with the 3 be taken away

hence;

x^7/y^3

hence 3 is then possitive

Answer 2

x^7/y^7 (top right)

Explanation:

Exponents are added together when multiplied, so it would equal x^7y^-7, but to get rid of the negative, the y would become the denominator in a fraction.
