4.Using only the and the operators, find a logical expression that is equivalent to ( ) . For this question, you do not need to specify "how" you found the equivalent expression because you will show both techniques in questions 5 and 6 below. (0.5 marks) (the square is the AND operator)

5. Prove that the expression you found for question 4 above is equivalent to the expression ( ) by using only truth tables. Show all your work and do not skip any steps (i.e., ensure you that you include a new column for every single operation).

6.Prove that the expression you found for question 4 above is equivalent to the expression ( ) by using only the logical equivalences. Show all your work and do not skip any steps.

(please answer both of those 3 questions thak you)
