Question

matrix A has 4 rows and 3 coloumns and matrix B has 5 rows and 2 columns the matrix AB will have​

Answer 1

Answer:

Concept :

In arithmetic, specially in linear algebra, matrix multiplication is a binary operation that produces a matrix from  matrices. For matrix multiplication, the range of columns inside the first matrix ought to be same to the quantity of rows in the 2nd matrix. The resulting matrix, called the matrix product, has the range of rows of the first and the quantity of columns of the second one matrix. The fabricated from matrices A and B is denoted as AB. Computing matrix products is a significant operation in all computational programs of linear algebra.

Explanation:

• The matrix AB will have 4 rows and 2 columns upon multiplication of the matrices A and B.
• The main circumstance of matrix multiplication is that the wide variety of columns of the 1st matrix ought to be equal to the number of rows of the 2nd one.
• Because of multiplication you may get a new matrix that has the equal quantity of rows because the 1st one has the same amount of columns as the second one.
• For instance in case you multiply a matrix of 'n' x 'k' through 'k' x 'm' size you may get a new one in all 'n' x 'm' size.
