Kiran can explain factoring to lin by finding what multiples together to get an expression. It is in a way, like splitting an expression into multiplication easier expressions.
Answer:
The (i,j) cofactor Cij of A is defined to be
Cij=(−1)ijdet(Mij),
where Mij is the (i,j) minor matrix obtained from A removing the i-th row and j-th column.
Then consider the n×n matrix C=(Cij), and define the n×n matrix Adj(A)=CT.
The matrix Adj(A) is called the adjoint matrix of A.
When A is invertible, then its inverse can be obtained by the formula
Step-by-step explanation:
The first one equals 0.00116
The second one equals 195,000
the third one equals 0.0286
and the fourth one equals 87,310,000,000,000,000
The smallest one is A 0.00116
