Question

What is the product?

Answer 1

So option B is the correct answer .

Explanation:

Since it is the multiplication of 1 X 3 matrix to 3 X 3 order matrix,

so the resultant product should be 1 X 3 because when we multiply two matrices it is the condition that if A is of order p X q and B is of order q X r,

the product matrix (suppose C ) will be of order p X r.

so the product will be

= [-1*3+2*2+4*0 -1*6+2*4+4*6 -1*1+2*0+4*2]

= [ 1 26 7] .
