$sqrt63$ , $sqrt44$ , and $sqrt48$ can be simplified...........

$sqrt63=sqrt7xxsqrt9=3sqrt7$

$sqrt44=sqrt4xxsqrt11=2sqrt11$

$sqrt48=sqrt12xxsqrt4=sqrt4xxsqrt3xxsqrt4=sqrt4^2xxsqrt3=4sqrt3$

On the other hand, $sqrt73$ is the square root of a prime number, and has no factors that are perfect squares.

Which of the following radicals are simplified: sqrt63, sqrt44, sqrt73, sqrt48sqrt63, sqrt44, sqrt73, sqrt48?
