Question

prove that 5+√5 is irrational
please step by step in copy​

Answer 1

Answer:

Let assume that 5+√5 is rational number.

5+√5 = a/b [where a,b are integers b≠0]

√5=a/b-5

√5=a-5b/b [by lcm]

where a-5b/b is rational number and √5 is a rational number.But contradicts that √5 is a irrational number and 5+√5 is irrational number.
