What is the result of the scalar 5 multiplied by the 2x2 identity matrix?

Question

Accepted Answer

Step:1 ：Step 1: Write down the 2x2 identity matrix [I = begin{bmatrix} 1 & 0  0 & 1 end{bmatrix}]Step:2 ：Step 2: Multiply every element in the identity matrix by the scalar 5 [5I = 5 times begin{bmatrix} 1 & 0  0 & 1 end{bmatrix} = begin{bmatrix} 5 & 0  0 & 5 end{bmatrix}]
