(sqrt3+5 sqrt6)(sqrt3-5 sqrt6)
DRWLS-Just take the difference of the squares of the two terms, sqrt 3 and 5 sqrt6. Then you will have the answer. It will be a negative integer.
3sqrt is 9
6sq rt is 36
I add 5 to one and subtract 5 from the other? 50 and 55, then I am supposed to multiply? 50x55=2750? Or is the difference -5?
sqrt 6 is not 36. You got that backwards
The squares of the two terms (sqrt 3 and 5sqrt6) are 3 and 150. The answer is 3-150 = -147
