Discrete Mathematics

Using proof by contraposition, show that if n is an integer and 5 added to its cube is odd then n is even. Before showing your solution, rewrite the statement to the proper form of a conditional statement then assign variables to the simple propositions. Show also the contrapositive form of the simple propositions before proceeding to your solution.

Discrete Mathematics

Use proof by contradiction to show that a number is even if its square is even. Before showing your solution, rewrite the statement to the proper form of a conditional statement. Assign variables to the simple propositions then write your assumption using these variables and logic symbols. At the end of your solution
