Thanks, so that  does not matter, cause Im supposed to add all of them, and the answer I got was 37 which is the exact same answer in my textbook.

Then your question should have been
√2(√512√3) + √3(√82√30)
If they have 37 for the way you typed it, then the book is wrong. Check your typing.
Of course the "" matters.

Oh Ok, so yeah the book is wrong, I checked again, and yeah that negative sign is an error in the book. That would have totally messed me up.
