    Simplifying Radicals (2)

    Radicals has screwed me again. Please can anyone show me how to simplify this.




    The answer should be (X^2+1/X2)^1/4

    My exam is in a few hours and quick help would be much appreciated.

    Thanks.

    1 + \frac{2x^2+1}{x^4}

    \frac{x^4}{x^4} + + \frac{2x^2+1}{x^4}

    \frac{x^4+2x^2+1}{x^4}

    \frac{(x^2+1)^2}{(x^2)^2}

    \left(\frac{x^2+1}{x^2}\right)^2

    now put it all to the 1/8 power and finish it
