Given matrix [tex]M[/tex] below, what element is in [tex]M_{3,1}[/tex]?

[tex]\[
\left[\begin{array}{cccc}
-49 & 12 & -14 & -41 \\
-35 & 34 & 37 & -19 \\
-34 & 49 & -10 & 32
\end{array}\right]
\][/tex]

Enter your answer as a whole number with no spaces.



Answer :

To determine the element in [tex]\( M_{3,1} \)[/tex] of the given matrix [tex]\( M \)[/tex], let's break down the task step-by-step:

Given matrix [tex]\( M \)[/tex] is:
[tex]\[ \begin{pmatrix} -49 & 12 & -14 & -41 \\ -35 & 34 & 37 & -19 \\ -34 & 49 & -10 & 32 \end{pmatrix} \][/tex]

The notation [tex]\( M_{3,1} \)[/tex] refers to the element in the 3rd row and the 1st column of the matrix.

1. Identify the 3rd row of the matrix:
[tex]\[ \begin{pmatrix} -34 & 49 & -10 & 32 \end{pmatrix} \][/tex]

2. Identify the 1st element in this row, which corresponds to the 1st column:
[tex]\[ -34 \][/tex]

Thus, the element [tex]\( M_{3,1} \)[/tex] is:
[tex]\[ \boxed{-34} \][/tex]
