Question 64132
The square root of 3 times itself is actually 3.  So you can write the top numerator as square root of 3 times the square root of 3.  Notice that the denominator has a square root of 3 as well.  One of the top cancels with the one in the denominator.  So you are left with 4 times the square root of three in the numerator, and just one in the denominator.

{{{ 3^(1/2) }}} = {{{ sqrt(3) }}}

{{{ 3^(1/2) * 3^(1/2) / ( 4 * 3^(1/2) ) }}} = {{{ 3^(1/2) / 4 }}}
