Question 200932
The square root of 4a divided by square root of 3b. 
:
{{{sqrt(4a)/sqrt(3b)}}}
:
Multiply by {{{sqrt(3b)/sqrt(3b)}}} (any number over itself is one)
{{{sqrt(4a)/sqrt(3b)}}} * {{{sqrt(3b)/sqrt(3b)}}}
:
Gets rid of the radical in the denominator
{{{sqrt(4a)*sqrt(3b)/(3b)}}} = {{{sqrt(12ab)/(3b)}}}
Factor inside the radical to reveal perfect square
{{{sqrt(4*3*a*b)/(3b)}}}
Extract the square root of 4, which is 2
{{{2*sqrt(3ab)/(3b)}}}
