If A is a square matrix of order 3 , then consider the following statements. I. If |A|=0 , then | Adj A|=0 II. If |A| 0 , then |A⁻¹ |=|A|⁻¹ Which of the above statements is/are true?

Step-by-step solution

For a square matrix A of order 3 , | Adj A|=|A|³⁻¹=|A|^2 If |A|=0 , then | Adj A|=0 and A A⁻¹=I , if |A| 0 aligned & |A A⁻¹ |=|I| |A| |A⁻¹ |=1 & |A⁻¹ |=|A|⁻¹ & aligned So, statements I and II, both are correct.
