Show that \(3\sqrt{2}\) is irrational.
 
Proof:
 
Let \(3\sqrt{2}\) is .
 
By definition, \(3\sqrt{2}\)
 
That is, \(3\sqrt{2}=\) be number, where \(p\) and \(q\) are and \(q\neq 0\)
 
On simplification we get, \(\sqrt{2}=\frac{\frac{p}{q}}{3}\)
 
Since, \(p\) and \(q\) are integers, \(\frac{\frac{p}{q}}{3}\) will also be .
 
Therefore, \(\sqrt{2}\) is .
 
This the fact that \(\sqrt{2}\) is .
 
Hence, \(3\sqrt{2}\) is .
