1. Problem Description

The problem asks to compute the scalar multiplication of a matrix. We are given M=13[1065]M = \frac{1}{3} \begin{bmatrix} 1 & 0 \\ -6 & 5 \end{bmatrix}. We need to find the matrix MM.

2. Solution Steps

To find MM, we need to multiply the scalar 13\frac{1}{3} with each element of the matrix [1065]\begin{bmatrix} 1 & 0 \\ -6 & 5 \end{bmatrix}.
M=13[1065]=[13(1)13(0)13(6)13(5)]M = \frac{1}{3} \begin{bmatrix} 1 & 0 \\ -6 & 5 \end{bmatrix} = \begin{bmatrix} \frac{1}{3}(1) & \frac{1}{3}(0) \\ \frac{1}{3}(-6) & \frac{1}{3}(5) \end{bmatrix}
Now, we perform the scalar multiplication:
13(1)=13\frac{1}{3}(1) = \frac{1}{3}
13(0)=0\frac{1}{3}(0) = 0
13(6)=2\frac{1}{3}(-6) = -2
13(5)=53\frac{1}{3}(5) = \frac{5}{3}
So, M=[130253]M = \begin{bmatrix} \frac{1}{3} & 0 \\ -2 & \frac{5}{3} \end{bmatrix}.

3. Final Answer

M=[130253]M = \begin{bmatrix} \frac{1}{3} & 0 \\ -2 & \frac{5}{3} \end{bmatrix}
