Question

if s=[sij] is a scalar matrices such that sii=k and a is a square matrix of the same order then as=sa=?

Answer 1

Answer:

AS=[kw kx

ky. kz]

Step-by-step explanation:

Let the square matrix A = [ w x

y z]

And S = [ k 0

0 k]

Then AS=SA= the answer above

Each and every element of square matrix A gets multiplied by the constant k of the scalar matrix S.
