do the indicated operations and write with only positive exponents and assume all variables are nonzero real numbers

x^-5 y^7/x^-2 y^5

y^2/x^3

x^3=0

• Algebra -

your x^-5 y^7/x^-2 y^5 should have said
x^-5 y^7/(x^-2 y^5) then it would be

but I don't see what the x^3=0 in your last line is supposed to be.
Is it supposed to say x^3 is not equal to zero??
then it should be placed after you second last line as a restriction.

• Algebra -

I meant to put y^2/x^3 as my answer. Is that correct?
