You can combine like terms when the amount under the radical (square root sign) is the same.
7 sqrt(2) + 5 sqrt(3) - 8 sqrt(2) =
(7-8) sqrt(2) + 5 sqrt(3) =
-sqrt(2) + 5 sqrt(3)

Question 1 √54 = √(9 x 6) = 3.√6 Question 2 √ (10/32) = √((2 x 5) / (2 x 16)) = [√(5/16) ] = (1/4).√5

7sqrt = 2.645751311
5sqrt3 = 1.709975974
8sqrt = 2.828427125
so = 2.65 + 1.71 - 2.83 = 1.53
got it ?
