Answer 1

The product of a non-zero rational and an irrational number is always irrational.

• A rational number is a number which can be expressed in the form p/q, where p and q are co-prime integers, and q is not equal to zero.
• A real number that cannot be expressed in the p/q form is an irrational number.
• For a rational number 'a' and an irrational number 'b', which are non-zero, ab is always irrational.
• For example, if a = 4 and b = √3, ab = 4√3, which is an irrational number.
