Answer 1

Answer:

Step-by-step explanation:

(15)

a+c√b=a/b(where a and b are coprime and b is not equal to zero)

a+c√b*a/b

c√b=a/b-a

c√b=a-Ab/b

√b=a-Ab/cb

So,where a-Ab/cb is a rational no. But √b is an irrational no. So,these contradiction and supposition is wrong hence a+c√b is irrational no.
