Truth table verification 10
Multi tool use
$begingroup$
The question:
Let $P$, $Q$, and $R$ be statements. Determine whether or not the two expressions in each pair are logically equivalent. In each case, demonstrate that your answer is correct.
a.) $(P ∧Q) ∧R, P ∧(Q ∧R)$
My attempt using truth table:
begin{array}{|c|c|c|c|}
hline
P& Q & P ∧ Q& R \ hline
T& T& T&T\ hline
F& T & F&F\ hline
T& F & F&F\ hline
F& F & F&F\ hline
end{array}
begin{array}{|c|c|c|c|}
hline
Q& R & Q ∧ R& P \ hline
T& T& T&T\ hline
F& T & F&F\ hline
T& F & F&F\ hline
F& F & F&F\ hline
end{array}
Therefore, they are equivelent.
Is this the correct method/approach to showing that the statements are correct using truth tables?

It is correct. Although, you might use the fact that $land$ is associative unless the problem specifically doesn't want you to do that. If that is the case, then the truth table is the only way.

@Forextrader Just to make the answer more complete, add one more column in the end for both tables, that includes the full expressions.
