Question

How do you simplify `5[(1/2,0,1),(2,1/3,-1)]+4[(-2,3/4,1),(1/6,0,5/8)]`?

Answer 1

`[(-11/2,3,9),(32/3,5/3,-5/2)]`

Explanation:

Each of the elements in the matrix is multiplied by the scalar.

`rArr[(5/2,0,5),(10,5/3,-5)]+[(-8,3,4),(2/3,0 ,5/2)]`

Now add corresponding elements in each matrix.

`rArr[(-11/2,3,9),(32/3,5/3,-5/2)]larrcolor(red)"is the sum"`
