Question

9. Give an example to show that the product of a rational number and an irrational number is a irrational number.

Answer 1

Answer:

Take a = (2+ √3) and b =(2 - √3 ); a and b are irrational numbers, but their product = 4-3 = 1, is a rational number. Take c = √3 and d = -√3; c and d are irrational numbers.
