Uh, that looks really complicated lol so u don’t think I’d be able to. Sorry ☹️
Well think of it like this. lets say your teacher made you do this problem -48 - 10. I would just act like 48 is not an negative and add 10. After that I would put the negative back. So the answer would be -58. :P
G mean = sqrt (3*48) = sqrt (3*3*4*4) = 3*4 = 12
