Question 30302
{{{ ( 72x^(3/4) )/( 8x^(1/4) ) }}} 


Well, first lets do 72/8 --> 9
{{{ ( 9x^(3/4) )/( x^(1/4) ) }}} 


Now for the x terms. We have powers and we are dividing, so by the rules of exponents/powers/indices, the powers will subtract: {{{ (3/4) - (1/4) }}} is {{{2/4}}} which is {{{ 1/2 }}}.


--> {{{ 9x^(1/2) }}} which MEANS {{{ 9sqrt(x) }}}. This is the final answer, written as a radical (or surd).
