This exercise asks you to prove a biconditional, from a contradiction. It looks complicated, but don't panic. Remember the rule of Introduction. You need two use two subproofs, one for each direction of the biconditional. And it would be a good idea to review the rules governing the contradiction symbol.Complete the proof on file labeled Exercise Bermudez $8\mathrm{.}3.$prf$,$ which you will find under the Instructor Files tab in Fitch $($Next to the Exercises tab, when you use the Open command$).$ You should save your solution as Proof Bermudez $8\mathrm{.}3.$prf$.$Exercise Bermude
