please type out your question using the equation toolbox. I can't make any sense out of your question

2^{2} X 20_{2}^{1} X 5_{2}^{3} = ???

it makes even less sense now. use the equation toolbox, it is a button below to the left of the post and attach file buttons.

ok so what does $20^{1/2}$ and $5^{3/2}$ equal to?

$x ^{a/b} = \sqrt[b]{x^{a}}$

and $\sqrt{ab}=\sqrt{a}\sqrt{b}$

$\sqrt{2}\times \sqrt{5^{3}}$ $\sqrt{2}\times \sqrt{5^{2}5}$ $5\sqrt{2}\sqrt{5}=5\sqrt{10}$
