Explanation / Answer

As per Chegg policy, I am answering only first 6 questions:

29.) 2*[1 4 5] = [2 8 10]; simple scalar multiplication

30.) [1 2; 3 4]*[2 1; 3 3] = [8 7; 18 15]

31.) [3 2 1].^2 = [9 4 1]

32.) 2.*[1 4 5] = [2 8 10]; scalar multiplication

33.) [1;3;4].*[2;1;2] = [2;3;8]

34.) [1 2; 3 4].*[2 1; 3 3] = [ 2 2; 9 12]

Hope it helps, do give your valuable response.
