What is the result of the scalar 5 multiplied by the 3x3 identity matrix?

Step 1 ：Write down the 3x3 identity matrix: \( I = \begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix} \)

Step 2 ：Multiply each element in the matrix by 5: \( 5I = \begin{bmatrix} 5 & 0 & 0 \\ 0 & 5 & 0 \\ 0 & 0 & 5 \end{bmatrix} \)
