Answer 2

Step-by-step explanation:

we have to prove that 3+2√5 is irrational number.

let us assume the opposite,

i.e,3+2√5 is rational.

hence,3+2√5 can be written in the form of p/q

where p and q (q=0) are co-prime (no common factor other than 1)

hence,3+2√5=p/q

2√5=p/q-3

2√5=p-3q/ q

so, now it is irrational number.
