Step-by-step explanation:
let we consider 3+2√5 is a rational number.
and the rational number are always written in the form of p/q
therfore,
3+2√5=p/q
√5=p/q-3-2
√5=p/q. Proved
√5 is a irrational number.
but we consider that 3+2√5 is a rational number.
hence,
our consideration is wrong 3+2√5 is a irrational number.
