Question

Please solve this question.

It's really urgent. I'll mark the correct solution as brainiest​

Answer 1

Answer:

A inverse of inverse is A itself

so |A|=8+3=11

hope it is correct

Answer 2

Step-by-step explanation:

If A = 2

[(2^-1)^-1] [(m^n)^p = m^n*p]

= 2 ^1

= 2

If A = -1

[(-1^-1)^-1] [(m^n)^p = m^n*p]

= -1^1

= 1

If A = 3

[(3^-1)^-1] [(m^n)^p = m^n*p]

= 3^1

= 3

If A = 4

[(4^-1)^-1] [(m^n)^p = m^n*p]

= 4^1

= 4
