{{{ sqrt((63x^15y^9 )/( 7xy^11)) }}}


Simplify the fraction inside the square root first.  Maybe good things will happen to you!!  Remember that when you divide, you must subtract exponents!

{{{ sqrt((9x^14)/y^2)) }}}  


Good things DID happen!!  Notice that everything inside the square root sign is a perfect square!!  Remember, when you take a square root of variables with exponents, you divide the exponents by 2!

{{{ sqrt(9x^14)/(sqrt(y^2)) }}}

{{{(3x^7)/y }}}
