If you know that a square root is the same as a power 1/2, then you can just apply the power/exponent rule.

which you can express with exponents,

$\displaystyle 2x^{1/2}+3x^{1/3}$

then, use the exponent rule,

$\displaystyle x^{-1/2}+x^{-2/3}$

$\displaystyle \left<\begin{array}{ccc}\mathbb{Q}&\ & \ \\ \ & \mathbb{E}& \ \\ \ & \ & \mathbb{D}\right>$
