Proof for matrix
This proof was confusing me so if anyone could show me how it is done, then i would appreciate it!
If A is a nonsingular matrix and c is in the set of real numbers w/ c not equal to 0, prove that the inverse of cA (meaning (cA)^-1) is equal to the inverse of A * (1/c).
I think you mean that,

Just show that,
This is true because c(1/c)=1
Thus this statement is true.
