needs to be simplified
first, I broke it down to
and 
simplifies to i ;and can be broken down to
and 
can be simplified further to 3
Now all you have to do is put it together
4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)
