Answer 1

Given :-

• $A=\left[\begin{array}{ccc}1&4\\5&6\\\end{array}\right]$
• a$_{ij}$ = 6

To Find :-

• Value of i and j

Solution:-

$\longrightarrow$In a matrix the the the position of an element is determined by using a$_{ij}$ where i the number of row and j is number of column in which the element is.

$\leadsto$Since 6 is in 2nd column and 2nd row , it's position can be written as a$_{22}$

Comparing with a$_{ij}$

• i = 2
• j = 2
