Question

prove that 3+5 root 2 irrational

Answer 1

Hope it is correct!!!!!

Answer 2

hi mate......
here is your answer

3+5√2

let 3+5√2 be rational and have only common factor 1.

Let, 3+5√2 = a/b
5√2 = a - 3/ b
5√2 = a-3b/b

if a - 3b / b is rational so, 5√2 is also rational
but it is not possible .
It is contradiction to our assumption .
so, 3+5√2 is a irrational.

hope it works to you..........
