If A= [ array lll 83 & 74 & 41 93 & 96 & 31 24 & 15 & 79 array ] , then det (A-A^ T )=

Options

  1. A0
  2. B-7851
  3. C2442
  4. D1

Correct answer

A. 0

Step-by-step solution

Since, A= [ array lll 83 & 74 & 41 93 & 96 & 31 24 & 15 & 79 array ]_ 3 3 Since, A-A^ T is always a skew symmetric matrix of order 3 (odd). So, det (A-A^ T )=0
