Q:

Bolding an item of a list

How would I bold just this item? Thank you.
\item $\neg f\to (\neg b\lor\neg m)$

A:

If you want to bolden the contents of the item, the simplest is this:
\item \boldmath$\neg f\to (\neg b\lor\neg m)$\unboldmath

or, following egreg's suggestion:
\item {\boldmath$\neg f\to (\neg b\lor\neg m)$},
