Number 6 and 7 could you all work ?

6) Given the three vectors A = 1.00 1 - 4.00 j, B = 3.00 i, and C = -2.00 / evaluate the following expressions if they are allowed mathematically: (a) C . (A + B); (b) C . (A . B); (C)C+ A . B 7) Given three vectors, A = 2.00 1 - 5.00 j, B = 4.00 j, and C = 3.00 f, evaluate the following expressions if they are mathematically allowed: (a) C(A x B); (b) C . (A x B) ; (c) CX (A . B)
