Step-by-Step Solution

The solution is $3$rd row and $5$th column.

Step 1. Given information.

The notation $a_{35}$.

Step 2. Fill up the blanks.

Compare $a_{35}$ with standard notation $a_{ij}$, where $i$ denotes for row and $j$ denotes for column.

So, $i=3$ and $j=5$.

Thus, third row and fifth column.

Step 3. Simplified answer.

Hence, the notation $a_{35}$ refers to the entry in the $3$rd row and $5$th column of a matrix.
