  1. For given matrix P = 4 + 3i-i where i = √-1, the inverse of matrix P is
    i4 - 3i

    1. 1
      4 - 3ii
      24-i4 + 3i

    2. 1
      i4 - i
      254 + 3i-i

    3. 1
      4 + 3i-i
      24i4 - 3i

    4. 1
      4 + 3i-i
      25i4 - 3i

Correct Option: A

P = 4 + 3i-i
i4 - 3i

P-1 = 4 - 3i-(-i)
-i4 + 3i
| A |

=
1
4 - 3ii
24-i4 + 3i
