Prove Root 13 irrational |
| Answer» Let us assume that √13 is rational no and equals to p/q are Co primes√13=p/qsquaring both sides√13*2=p*2/q*213=p*2/q*213q*2=p*213/p*213/pp=3r for some integer rp*2=169r*213q*2=169*2b*2=13r*213/b*213/b13 is a common factor but this is contradiction hence our supposition is wrong √13 is irrational no. | |
