Question

If A= 1 0 0 , 5 1 0, 1 3 1 then find matrix B such that AB =I verify that BA =I

Answer 1

Answer:

$\huge \fbox\pink{answEr}$

n×n matrix A is said to be invertible if there exists an n×n matrix B such that

AB=I, and

BA=I,

where I is the n×n identity matrix.

If such a matrix B exists, then it is known to be unique and called the inverse matrix of A, denoted by A−1.
