• The variable for the given two matrices A=[1432] and C=[325412] and perform the operation “A*C”.

• To find whether other multiplication operation can be performed in part 2 or not.

Answer to Problem 45E

Solution:

• The variable for the given matrix A=[1432] is “A = [1 4; 3 2]”, and the output of the operation “3*A” is [31296].

• The variable for the given two matrices A=[1432] and C=[325412] are “A = [1 4; 3 2]” and “C = [3 2 5; 4 1 2]”. The output of the operation “A*C” is [1961317819].
