    Re: Radicals Help

    hi grande punto

    that is not an equation,so you can't really solve it!

    if you want to simplify it then:
    \sqrt[4]{x^4+x^2+\frac{1}{4}}=\sqrt[4]{(x^2+\frac{1}{2})^2}=\sqrt{x^2+\frac{1}{2}}

    Re: Radicals Help

    try expanding (x^2 + 1/2)^2,and then try expanding (x^2 +1+1/2)^2=(x^2 + 3/2)^2. See what you get.

    Also i didn't realise that you had a in your radical and not x.sorry about that!
