WebbSolution Verifying whether π is a rational or an irrational number: Rational numbers are the numbers which can be expressed in the form p q where p, q are both integers and q ≠ 0. When expressed in decimal form, rational numbers are terminating decimals or repeating in an fixed pattern For example: Webb17 apr. 2024 · This tautology shows that if $\urcorner X$ leads to a contradiction, then $X$ must be true. The previous truth table also shows that the statement $\urcorner X \to C$ is logically equiva lent to $X$. This means that if we have proved that $\urcorner X$ leads to a contradiction, then we have proved statement $X$. So if we want to prove a …
