Question 72196
<pre>
Problem #2
sqrt 50 

{{{sqrt(50)}}} = {{{sqrt(25*2)}}}

      = {{{sqrt(25)}}} * {{{sqrt(2)}}}

      = {{{(5) sqrt(2)}}} 



Problem #24 
{{{sqrt (72x^3)}}} = {{{sqrt(36*2*x^2*x)}}}

           = {{{sqrt(36)}}}* {{{sqrt(2)}}}* {{{sqrt(x^2)}}}* {{{sqrt(x)}}}

           = {{{(6x) sqrt(2x)}}}
