Answer 2

to prove: - 7 root 5 is irrational

to the contracy let us assume 7 root 5 Is rational ..

a rational is of the form p/ q
so 7 root 5 = p/q (where q ≠ 0)
7 root 5 = a/ b ( after simplify the p/q or the simplest form)

root 5 = a/7b
as we know root 5 is irrational

hence root 5 is irrational, and a/7b is rational
an irrational cannot be rational...

hence we say that 7 root 5 is rational ...
