Explanation opens after your attempt
Correct Answer
A. \(A=\begin{bmatrix}1&2\1&2\end{bmatrix}\)
Step 1
Concept
In \(a_{ij}=j\), each element equals the column number. So each row becomes (1,2).
Step 2
Why this answer is correct
The correct answer is A. \(A=\begin{bmatrix}1&2\1&2\end{bmatrix}\). In \(a_{ij}=j\), each element equals the column number. So each row becomes (1,2).
Step 3
Exam Tip
\(a_{ij}=j\) में अवयव स्तंभ संख्या के बराबर होता है। इसलिए हर पंक्ति में (1,2) आएगा।
