Answered by BabyBunny

Answer:

a) Irrational

b) Rational

Step-by-step explanation:

a) Let 5+√2 be a rational number, ... Therefore,p,q are integers then (p-5q)/q is a rational number. Then √2 is also a rational number. But this contradicts the fact that √2 is an irrational number.

b) Therefore, (3-√3)(3+√3) is a rational number.
