We can prove 1by root 7 irrational by contradiction . Let us suppose that 1by root7 is rational it means we have some co-prime integers a and b (b is not equal to 0)such that 1by root 7=a/b Root7=b/a .....1 RHS of 1 is irrational but we know that root7 is irrational. It is not possible which means our supposition is wrong. Therefore,1by root7 cannot be rational.. Hence it is irrational..
