cannot be expressed as p/q form
co-primes
\(\sqrt{7}\) is a rational
satisfies
\(\sqrt{7} = \frac{p}{6q}\)
contradicts
Let's prove is an irrational number.
Now prove by contradiction method.
| 1. | Assume 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, is |
