Hello dingolove
I don't get what your problem with this is.
Don't you know how to extract the square root of a number?
Than have a look here (link) (http://wiki.answers.com/Q/How_do_you_extract_square_roots_by_algebraic_Manip ulation)
The square root of a number is another number that - multiplied with itself - produces that number again.
So √100 = 10, as 10 x 10 = 100 , and √81 = 9, as 9 x 9 = 81
If you followed the link than you can calculate now :
√108 =...
√75 =...
So √108 + √75 =... +... =...
