Question

construct a 4*3 matrix whose elements are: i) aej=2i+e/f

Answer 1

The required matrix is =   3     4     5

                                            5     6     7

                                            7     8     9

                                            9     10   11

Step-by-step explanation:

The question has an error. A matrix usually has two components and the elements are represented as a which is a factor of i and j. So the question should actually be aij = 2i + j.

Please find below the solution based on the corrected question.

So we have four rows and three columns in the matrix.

aij = 2i + j

a11 = 3

a12 = 4

a13 = 5

a21 = 5

a22 = 6

a23 = 7

a31 = 7

a32 = 8

a33 = 9

a41 = 9

a42 = 10

a43 = 11

So the required matrix is =   3     4     5

                                                5     6     7

                                                7     8     9

                                                9     10   11
