The given expression is a matrix with four rows and four columns. To find the value of this expression, we need to perform the operations indicated by the numbers in the matrix.

Starting with the first row, we have the numbers 67, 19, 21, and 39. We can interpret these numbers as a series of operations to be performed on the second row of the matrix. Specifically, we can think of them as follows:

67: Take the number in the second row and multiply it by 67. 19: Take the number in the second row and multiply it by 19. 21: Take the number in the second row and multiply it by 21. 39: Take the number in the second row and multiply it by 39.

Performing these operations gives us the numbers 13, 14, 26, and 24 in the second row.

Next, we move on to the third row of the matrix, which contains the numbers 81, 24, 26, and 14. We can interpret these numbers as a series of operations to be performed on the fourth row of the matrix. Specifically, we can think of them as follows:

81: Take the number in the fourth row and multiply it by 81. 24: Take the number in the fourth row and multiply it by 24. 26: Take the number in the fourth row and multiply it by 26. 14: Take the number in the fourth row and multiply it by 14.



Finally, we sum up the numbers in the fourth row to get the value of the expression, which is -43.
