(P \(\lor\) R) \(\Rightarrow\) Q}
(P \(\Rightarrow\) R) \(\lor\) (Q \(\Rightarrow\) R)}
(P \(\Rightarrow\) R) \(\land\) (Q \(\Rightarrow\) R)
(P \(\land\) R) \(\Rightarrow\) Q
We are given the statement (P \(\Rightarrow\) Q) \(\land\) (R \(\Rightarrow\) Q). We know that P \(\Rightarrow\) Q is equivalent to \(\neg\)P \(\lor\) Q. So, the given statement can be written as: \[ (\neg P \lor Q) \land (\neg R \lor Q). \] Using the distributive law, we can rewrite this as: \[ (\neg P \land \neg R) \lor Q. \] Using De Morgan's law, \(\neg P \land \neg R\) is equivalent to \(\neg(P \lor R)\). So the statement becomes: \[ \neg(P \lor R) \lor Q. \] This is equivalent to (P \(\lor\) R) \(\Rightarrow\) Q.
Which one of the following graphs accurately represents the plot of partial pressure of CS₂ vs its mole fraction in a mixture of acetone and CS₂ at constant temperature?

Let \( \alpha = \dfrac{-1 + i\sqrt{3}}{2} \) and \( \beta = \dfrac{-1 - i\sqrt{3}}{2} \), where \( i = \sqrt{-1} \). If
\[ (7 - 7\alpha + 9\beta)^{20} + (9 + 7\alpha - 7\beta)^{20} + (-7 + 9\alpha + 7\beta)^{20} + (14 + 7\alpha + 7\beta)^{20} = m^{10}, \] then the value of \( m \) is ___________.
