Solve the matrix, then find A² + AC – 5B.

If A = and B = , C =
Find A² + AC – 5B

Solution:

If A = , find A2 and A3.Also state that which of these is equal to A

Solution:

More Solutions:

• Find the matrix C such that AC = B.
• Find matrix B such that BA = I, ,where I is unity matrix of order 2
• If A = [aij]2×2 where aij = i + j, then A is equal to.
• Then the values of x and y are x = 2, y = 3
• Then the value of x – y is (- 3).
• Then the matrix A is equal to.
