ANSWER:
- (2+√3) is an irrational number.
GIVEN:
- Number = 2+√3
TO PROVE:
- 2+√3 is an Irrational number.
SOLUTION:
Let (2+√3) be a rational number which can be represented in the form of p/q where p and q have no common factor then 1.
Here:
- (p-2q)/q is rational but √3 is an irrational number.
- Thus our contradiction is wrong.
- So (2+√3) is an irrational number.
NOTE:
- This method of proving and irrational number is called contradiction method.
- In this method we first contradict a fact and prove that our supposition was wrong.
