## anonymous one year ago Simplify square root of 2 multiplied by the cube root of 2.

1. anonymous

$\sqrt{2}*\sqrt[3]{2}$

2. anonymous

Is it like that?

Change each radical to rational expression. $\sqrt{2}-->2^{\frac{ 1 }{ 2 }}$ $\sqrt[3]{2}-->2^\frac{ 1 }{ 3 }$ Then use LCD in both fractions.
