how are the entries of the matrix named by position?

Answer:
3 is a13
1 is a31
5 is a14
Step-by-step explanation:
The positions on the matrix are all reflective of these names.
The position of the given numbers in the matrix is required.
The number 3 is at location [tex]a_{13}[/tex], number 1 is at [tex]a_{31}[/tex] and number 5 is at [tex]a_{14}[/tex].
The entries of a matrix are named in the following way
[tex]\begin{bmatrix}a_{11} & a_{12} & a_{13} & a_{14} & a_{15}\\a_{21} & a_{22} & a_{23} & a_{24} & a_{25}\\a_{31} & a_{32} & a_{33} & a_{34} & a_{35}\end{bmatrix}[/tex]
So, the number 3 is at location [tex]a_{13}[/tex], number 1 is at [tex]a_{31}[/tex] and number 5 is at [tex]a_{14}[/tex].
