Step 1
Given matrix expression:
[112]{[410][23]+[100111]}
Step 2
Using BODMAS rule first solve bracket then multiplication and then addition:
Multiplying [410] and [23] multiplication is possible because columns of first matrix is equal to the rows of the second matrix, we get: [112]{[4×24×31×21×30×20×3]+[100111]}
[112]{[8122300]+[100111]}
Add the matrices,we get:
[112]{[8+112+02+03+10101]}
[112][9122211]
Multiply the matrices,we get: [1×9+(1)×(2)+2×(1)1×12+(1)×(2)+2×(1)]
[9+2212+22]
[912]
Step 3
Therefore, the solution of the given matrix is [912]
