Question

2 by root 7 prove that is irrational​

Answer 1

Answer:

To prove 2/root 7 is irrational, you have to show that root 7 is irrational, as you know that when a rational number is divided by irrational no. then the no. obtained is irrational. We can do this by method of contradiction. => root 7 =p/q, where p and q are coprimes and q is not equal to 0. ... So 2, a rational no.
