Question

Prove that 3 + √5 is an irrational number​

Answer 1

Answer:

3 + rt5 =p/q is a rational no assume

3 + rt5 =p/q is a rational no assume Rt5 = p/q - 3

3 + rt5 =p/q is a rational no assume Rt5 = p/q - 3 Therefore Rt5 is irrational no we know that.

3 + rt5 =p/q is a rational no assume Rt5 = p/q - 3 Therefore Rt5 is irrational no we know that. But here it implies that it is a rational no

3 + rt5 =p/q is a rational no assume Rt5 = p/q - 3 Therefore Rt5 is irrational no we know that. But here it implies that it is a rational no So that our assumption is wrong.

3 + rt5 =p/q is a rational no assume Rt5 = p/q - 3 Therefore Rt5 is irrational no we know that. But here it implies that it is a rational no So that our assumption is wrong. Therefore proved.
