The Answer of Determine whether the argument is valid or invalid by using the Shortcut Method
-$ \begin{array}{l}\mathrm{Q} \vee \sim \mathrm{E} \\underline{ \sim \mathrm{Q}} \ \therefore \sim \mathrm{E}\end{array} $

Determine Whether the Argument Is Valid or Invalid by Using Q∨∼E∼Q‾∴∼E \begin{array}{l}\mathrm{Q} \vee \sim \mathrm{E} \\\underline{ \sim \mathrm{Q}} \\ \therefore \sim \mathrm{E}\end{array} Q∨∼E∼Q​∴∼E​
