    how is this equal to each other?

    How is \frac {3x^3}{x^3+1} = \frac {3}{1+\frac {1}{x^3}}?

    If this is not true the initial equation I used was \frac {3x^2}{x^3+1} \frac {1}{x}}

    That is basic grade school algebra.
    If you have trouble with that, you have no reason to be doing calculus.
