If ( A = begin{bmatrix} 2 & 4 1 & 3end{bmatrix} ), find the result of the scalar multiplication ( 5A ).

Question

Accepted Answer

Step:1 ：Firstly, we write down the matrix A: ( A = begin{bmatrix} 2 & 4 1 & 3end{bmatrix} ).Step:2 ：Scalar multiplication involves multiplying every entry of the matrix by the scalar. So, we multiply every entry of A by 5: ( 5A = 5 * begin{bmatrix} 2 & 4 1 & 3end{bmatrix} )Step:3 ：Carrying out the multiplication gives us: ( 5A = begin{bmatrix} 5*2 & 5*4 5*1 & 5*3end{bmatrix} )Step:4 ：Simplifying that, we get the final answer: ( 5A = begin{bmatrix} 10 & 20 5 & 15end{bmatrix} )
