Question

For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional.

If x = 3, then x2 = 9.

If x2 = 3, then x = 9.
If x2 = 9, then x = 3.
If x2 = 9, then x = 3.
x2 = 9 if and only if x = 3.
If x2 = 9, then x = 3.
x=3 if and only if x2 = 9.
