Logical equivalence question $(M \vee B) \wedge (H \vee B) \wedge (H \vee M)$ is a formula where $\wedge$ is the symbol for AND. 
What I need to know is: is there any equivalent formula to this one?  

$$(M \lor B)\land (H \lor B) \land (H \lor M)\tag{1}$$
$(1)$ is expressed in Conjunctive Normal Form (CNF), which in some contexts is the desired form and simplification of a proposition. It cannot be further simplified in conjunctive normal form.
$(2)$ Another equivalent form is known as Disjunctive Normal Form (DNF) and is given by:
$$(M \land B) \lor (H \land B) \lor (H \land M)\tag{2}$$
Again, this cannot be further simplified in disjunctive normal form.
You might want to experiment with computing the truth-tables for each of $(1), (2)$ to see that they are indeed equivalent.
NOTE: There are indeed other ways to express the proposition given by $(1)$, but conjunctive normal form and disjunctive normal form are two very prominent forms used to express propositions.
