The value of the determinant $\left|\begin{array}{ccc}85 & 15 & 30 \\ 1 & 3 & 4 \\ 17 & 3 & 6\end{array}\right|$ is: |
2 -1 0 1 |
0 |
The correct answer is Option (3) → 0 $Δ=\left|\begin{array}{ccc}85 & 15 & 30 \\ 1 & 3 & 4 \\ 17 & 3 & 6\end{array}\right|$ elements of $R_1$ and $R_3$ are proportional $⇒Δ=0$ |
