Hi there,
I have tried this problem to this point...how to do further?
\({5+{1\over x^3}}\over{-4\over y^2}+3 \)
\(= {{5x^3+1}\over{x^3}}/{{-4+3y^2}\over{y^2}}\)
\(= {{5x^3+1}\over x^3} * {{y^2}\over -4+3y^2}\)
\(= {5x^3y^2+y^2}\over -4x^3+3x^2y^2\)
\(=2+y^2\over -4x^3+1\)
Is this the answer?..Thanx to anyone who is willing to assist..

The second last line looks right but the last line is not correct. :/ (why did you think it was?)
I don't think you can go further than the second last line. I might leave the factorising in but it doesn't matter.
Hi Melody,
it's me, Juriemagic...
uhm, well, this problem is actually one I found on the link you posted me a few days ago on negative indices. I actually notice now that I made an error. I should have had the last line as \(= {2x+y^2}\over-4x^3+1\)
because I'm thinking that the \({5x^3y^2}\over 3x^2y^2\) leaves \({2x}\)?
