Let's prove 731 is an irrational number.
 
Now prove by contradiction method.
 
1. Assume 731 is a
2. By the definition,
3. And \(p\) and \(q\) are
4. So we can write it as
5. Simplifying the term,
6. This implies that,
7. This
 our assumption.
8. Thus, 731 is
 
Answer variants:
can be expressed as p/q form
cannot be expressed as p/q form
\(\frac{7q - p}{q} = \sqrt{31}\)
co-primes
contradicts
irrational Number
satisfies
rational Number
\(\frac{7q - p}{q}\) is rational
\(7 - \sqrt{31} = \frac{p}{q}\)
