Verified by Experts

`a rarr q, b rarr p, c rarr s, d rarr r`.
a. `|A|=2implies |2A^(-1)|=2^(3)//|A|=4`
b. `|"adj (adj (2A))"|=|2A|^(4)=2^(12)|A|^(4)=2^(12)//2^(12)=1`
c. `(A+B)^(2)=A^(2)+B^(2)`
`implies AB+BA=O`
`implies |AB|=|-BA|=-|BA|=-|AB|`
`implies |AB|=0`
`implies |B|=0`
d. Product ABC is not defined.
