Question

Construct a matrix of 2X2 IN WHICH aij= 2i+3j

A) | 1 2 |
| 3 4 |

B) | 2 3 |
| 4 5 |

C) | 3 1 |
| 5 2 |

D) | 4 3 |
| 6 5 |

Answer 1

The correct matrix is option C) | 3 1 || 5 2 |

Step-by-step explanation:

The given matrix is:

| 2i + 3j | 2(1) + 3(2) | 2(1) + 3(4) |

| 2(2) + 3(1) | 2(2) + 3(2) | 2(2) + 3(4) |

Simplifying the matrix gives:

| 8 10 |

| 7 10 |

So the correct matrix is:

Option C) | 3 1 |

| 5 2 |
