Reference no: EM13322822

Q 1: Determine wheather of the statement true or false:
1- x^2+y^2=z^2 is not proposition.
2-the conditional statement p→q is false when both p and q are false.
3-~(~p?∼q) and p?q are logically equivalent.
4-p?~p is a contradiction.
5- the biconditional statement p↔q is false when both p and q are false.
