Answer:
x^7/y^7 (top right)
Step-by-step 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.
x^7/y^3
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;
hence 3 is then possitive
