Given X 3 2 Y 1 0 3 Z 2 5 2 0 4 5 2 1 4 3 0 Find x1 mean

Given X = (3 2) Y = (1 0 3) Z = (2 5)

(2 0) (4 5 2) (-1 4)

(3 0) Find x^-1 ( meaning the inverse of x ) 3X + (YZ)X

Solution

x^-1 ( meaning the inverse of x ) 3X + (YZ)X

=x^-1 3X + (YZ)X

=3 X^-1 X+(YZ)X

=3e+(YZ)X since X^-1 X=e

=3+(YZ)X
