Question

A is a matrix of 3* 3 and determinant of a is 10 then adjoint of a is

Answer 1

Hey!!!!....here is ur answer

first we find the inverse of matrix A

then as we know that.....inverse of A=adjA/|A|

so the adjoint of the matrix A is

adjA=Inverse of A ×|A|

adjA=10÷A^-1

hope it will help you ☺
