ANSWER:
- √5+3 is an Irrational number.
GIVEN:
- Number = √5+3
TO PROVE:

SOLUTION:
Let √5+3 be a rational number which can be expressed in the form of p/q where p and q have no other common factor than 1.
Here:
- (p-3q)/q is rational but √5 is an Irrational number.
- Thus our contradiction is wrong.
- √5+3 is an Irrational number.
