Question

Multiplicative inverse of a-b

Answer 1

Answer:

Multiplicative Inverse of a Non-singular Matrix

Then A and B are said to be multiplicative inverse of each other if AB = BA = I. The inverse of A is denoted by A-1 , thus AA–1 = A–1 A = I. Inverse of a matrix is possible only if matrix is non-singular.

Answer 2

Answer:

$\frac{1}{a-b}$

Step-by-step explanation:

a-b x $\frac{1}{a-b}$ = 1

Hence it is the multiplicative inverse of a-b
