Question

If A is a scalar matrix with scalar '2' of order 4, then the determinant det(A) will be?

a) 2
b) 4
c) 8
d) 16

Answer 1

The determinant of a scalar matrix with scalar '2' of order 4 is 16.

Step-by-step explanation:

To find the determinant of a scalar matrix, you simply raise the scalar to the power of the matrix order. In this case, the scalar is 2 and the matrix order is 4, so det(A) = 2^4 = 16. Therefore, the answer is d) 16.
