    8=2(4) \[\frac{2}{8}=\frac{2(1)}{2(4)}=\frac{\cancel{2}(1)}{\cancel{2}(4)}\]

    I think I see two problems above.. \[\sqrt[a]{x^b}=x^\frac{b}{a} \\ \text{ just use this for the other question }\]

    you could use \[\sqrt[a]{x^b}=x^\frac{b}{a}\] tried that

    notice when comparing 2^(1/4) to x^(b/a) x is 2 b is 1 a is 4

    \[\frac{2^\frac{3}{4}}{2^\frac{1}{2}}=2^{\frac{3}{4}-\frac{1}{2}}=2^{\frac{3}{4}-\frac{2}{4}}=2^{\frac{1}{4}}=\sqrt[4]{2^1}\] but remember 2^1 is just 2 so you have \[\sqrt[4]{2}\]
