Question

if A(1,1) B(0,0)and C(a,b) then the correct relation among the following is​

Answer 1

Answer:

Answer

Correct option is

B

B should be equal to C.

The matrix A cannot have two inverse. Suppose BA=I and AC=I then B=C. According to this proof by parentheses:

B(AC)=(BA)C

This implies BI=IC

Therefore B=C

This shows that a left-inverse B (multiplying from the left) and a right-inverse C (multiplying A from the right to give AC=I) must be the same matrix.
