a) p^q is sometimes true
b) p^q is true
c) Not enough information is provided.
d) p^q is false

Answer 1

The truth value of p^q when x is replaced by 81 is false.

Step-by-step explanation:

The truth value of p^q when x is replaced by 81 can be determined by substituting the value into the given statements. The statement p: x is a perfect square is true since 81 is a perfect square (9 squared). The statement q: x is even is false since 81 is not an even number. Therefore, the truth value of p^q is false.
