    @Marc1313 remember to use ^ to indicate exponential. Example, 3^x to mean \(3^x\)

    \[\sqrt[3]{x ^{3}}=\sqrt[3]{\frac{ 1 }{ 8 }}\] \[x^{3/3}=\frac{ 1 }{ 8 }^{1/3}\] \[x ^{1}=1/2\] \[x=1/2\]

    im not sure but i think we get \[\pm 1/2\] IF we get the SQUARE root of the value: 1/8 @mathmate is it 1/2 or \[\pm 1/2\]? :)
