Which of the following matrices is not a square-matrix?
- A [1]
- B \(\left[\begin{array}{ll}2 & 2 \\ 2 & 2\end{array}\right]\)
- C \(\left[\begin{array}{lll}3 & 3 & 3\end{array}\right]\)
- D \(\left[\begin{array}{lll}1 & 1 & 1 \\ 1 & 1 & 1 \\ 1 & 1 & 1\end{array}\right]\)
Answer & Solution
Correct Answer
(C) \(\left[\begin{array}{lll}3 & 3 & 3\end{array}\right]\)
Step-by-step Solution
Detailed explanation
