If the matrix $\begin{bmatrix}2 & 4 & 5\\4& 2& 3\\K & 3 & 2\end{bmatrix}$ is a symmetric matrix, then the value of K is : |
-5 0 5 1 |
5 |
The correct answer is Option (3) → 5 $\begin{bmatrix}2 & 4 & 5\\4& 2& 3\\K & 3 & 2\end{bmatrix}=\begin{bmatrix}2 & 4 & K\\4& 2& 3\\5 & 3 & 2\end{bmatrix}$ $⇒K=5$ |
