First assume the given equation is rational
Rational numbers cand be expressed in the form p square / q square
Step-by-step explanation:
Equate the 2/root 5 with it
take 2 to the right side
in the left we have 1/root5=p square/q spuare by 2
we know rational divided by rational is rational
but this contradict the fact that root 5 is irrational
so our assumption in wrong
thus2/root5 is irrational
