Question

How do you find ZY given `X=[(4,1), (-2,6)]` and `Y=[(0,-3)]` and `Z=[(-1,3), (0,-2)]`?

Answer 1

Matrix multipliction `ZY" is undefined."`

Explanation:

Here.

#Z=[(-1,3),(0,-2)]=>color(red)("a matrix Z has 2 rows and 2 columns ."#

`Y=[(0,-3)]=>color(blue)("a matrix Y has 1 rows and 2 columns ."`

Hence,

`color(red)("Number of columns in Z"` `!=` #color(blue)("Number of rows inY "#

So, matrix multipliction `ZY "is undefined."`
