Multiply the Matrices [[3],[4]]*[[9,4],[3,7]]

Problem

[[3],[4]]*[[9,4],[3,7]]

Solution

1. Check the dimensions of the matrices to see if multiplication is possible. The first matrix is a 2×1 matrix and the second matrix is a 2×2 matrix.

2. Determine compatibility by comparing the number of columns in the first matrix to the number of rows in the second matrix.

3. Identify the mismatch where the first matrix has 1 column and the second matrix has 2 rows.

4. Conclude that since the number of columns in the first matrix does not equal the number of rows in the second matrix, the operation is undefined.

Final Answer

[[3],[4]]*[[9,4],[3,7]]=Undefined
