Question

prove that 5+√5 is an irrational number​

Answer 1

Answer:

hey mate, here is your answer

let us assume that 5+√5 is an rational number that can be written in the form of a/b.

5+√5=a/b

√5=a/5b

so, 5+√5 is an rational number but it contradicts our fact that √5 is an irrational number.so, our assumption is wrong, 5+√5 is an irrational number.
