Question

What is the address of the element -5 in the matrix below?

1.) b22
2.) b23
3.) b32

none of these

Answer 1

The correct answer option is 3) b32.

Explanation:

We are given the following matrix:

`\left[\begin{array}{ccc}5&-6\\0&1\\3&-5\\-1&7\end{array}\right]`

and we supposed to find the address of the element -5 in it by using the following formula:

`b_m_n`

where
`m` is number of row; and

`n` is number of colums.

We can see that element -5 is in the third row and second column of the matrix.

Therefore, the address of element -5 will be
`b_3_2`.

Answer 2

we have to find address of element -5 in the matrix

We know that

horizontal line represents number of rows

vertical line represents number of columns

We can see that

-5 is in third row

and -5 is in second column

Suppose, we have element in matrix

`b_m_n`

Here , m is number of rows

and n is number of columns

so, we got

`m=3`

`n=2`

now, we can plug these values

and we get

`b_3_2`............Answer
