Question

Multiply
16 ab × 15 xy ​

Answer 1

Answer:

Consider matrix A which is a × b matrix and matrix B, which is a b ×c matrix.

Then, matrix C = AB is defined as the A × B matrix.

An element in matrix C, Cxy is defined as Cxy = Ax1By1 +….. + AxbBby =  ∑bk=1  AxkBky  for x = 1…… a  and y= 1…….c

This is one of the most important topics in class 12. Matrices for class 12 explains the types of matrices in detail.

Notation

If A is a m×n matrix and B is a p×q matrix, then the matrix product of A and B is represented by:

X = AB

Where X is the resulted matrix of m×q dimension.
