    This is what you have written above: \(\lim{\sqrt{x}-2}\) as \(x\rightarrow 4\sqrt{x^3}-8\); unfortunately, this doesn't make sense. (\(x\) can't approach something involving \(x\)). Could you re-check what you've written please?

    Then it's a typo. Is it from a book?

    In what was posted above, somehow the division bar got lost.

    then use the formula: \(\Large a^3 - b^3 = (a-b)(a^2+ab+b^2)\)

    It falls out nicely using l'Hopital's rule; too bad they specified a particular method!
