# If and find (3A2 – 2B + I).

Given : and Matrix A is of order 2 2, Matrix B is of order 2 2

To find : 3A2 – 2B + I

Formula used : Where cij = ai1b1j + ai2b2j + ai3b3j + ……………… + ainbnj

If A is a matrix of order a b and B is a matrix of order c d ,then matrix AB exists and is of order a d ,if and only if b = c

A2 = = = A2 = 3A2 = 3 × = 3A2 = 2B = 2 × = 2B = I = 3A2 – 2B + I = + = 3A2 – 2B + I = 3A2 – 2B + I = Rate this question :
