Question
Rank of the matrix $A=\left(\begin{array}{ccc}1 & 2 & 3 \\ 4 & 5 & 6\end{array}\right)$.(A) 1(B) 2(C) 3(D) 4
Step 1
The determinant of a 2x2 matrix is given by the formula: det(A) = ad - bc, where a, b, c, and d are the elements of the matrix. However, in this case, we have a 2x3 matrix, so we cannot directly find the determinant. Show more…
