Multiply the Matrices [[2,3],[6,5]]*[[4,2,4],[3,5,2],[2,1,3]]
Problem
Solution
Check dimensions for matrix multiplication. The first matrix is
2×2 and the second matrix is3×3 Identify the rule for matrix multiplication. For the product
A*B to exist, the number of columns inA must equal the number of rows inB Compare the values where the first matrix has
2 columns and the second matrix has3 rows.Conclude that since
2≠3 the matrices cannot be multiplied.
