I'm trying to solve this but I haven't seen syntax like this before. Can someone please explain the syntax?
The image is
Show that the one-to-one function $f^{-1} : N_{10} \Rightarrow N_b $ is the inverse of $f: N N_{b} \Rightarrow N_{10}$.
Hint: Show that $f^{-1} (f (n_b) ) = n_b$
I'm not sure how to format math on stackexchange either, so if someone could add what's in the png that would be great as well.
This is from a worksheet of things I should know before entering an assembly language class next semester.
Thanks!
