Question

If A=
`\left[\begin{array}{ccc}1&4\\5&6\\\end{array}\right]` and aij =6 then find the value of i and j

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
