Boolean algebra serves to relate logical quantities. The Boolean expression for the OR operation is C = A + B. Look up and write the Boolean expression for the AND operation. Write the truth table of the three-input operation D = A + (BC). Using truth tables, show that NOT(A + B) = (NOT(A))(NOT(B)) and similarly that NOT(AB) = ?

Directions. Determine whether the following three arguments are valid using the truth table method. Use the Indirect Truth Table method as found in the link on Canvas. Indicate whether each is valid or not. Note that ‘//’ is used as the conclusion indicator and ‘/’ is used to separate the premises. [Note: Use only the following logical symbols: ‘&’ for conjunctions, ‘v’ for disjunctions, ‘->’ for conditionals, ‘<->’ for biconditionals, ‘~’ for negations.] Show your truth tables. 1. (S <->...

Indirect Proofs: Prove Problems 5 - 7 using either proof by contradiction or proof by contraposition. AT LEAST ONE MUST USE PROOF BY CONTRADICTION! 7) For integers c, if c = ab and the ged(a,b) = 1, then a and b are perfect squares. (Hint: If a and b are not perfect squares, what type of number are they?)
