Answer:

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.

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
