Final answer:

To find the determinant of the matrix and determine if it has an inverse

Step-by-step explanation:

To find the determinant of a 3x3 matrix, you can use the formula:

determinant = a(ei - fh) - b(di - fg) + c(dh - eg)

For the given matrix [0 1 0], [2 6 4], [1 0 3], the elements are:

  • a = 0
  • b = 1
  • c = 0
  • d = 2
  • e = 6
  • f = 4
  • g = 1
  • h = 0
  • i = 3

Plugging these values into the formula, we get:

determinant = 0(6 * 3 - 0 * 0) - 1(2 * 3 - 4 * 0) + 0(2 * 0 - 6 * 1) = 0 - 6 + 0 = -6

Since the determinant is not equal to 0, the given matrix has an inverse.
