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

1.rational.
2.irrational.
3.a repeating decimal.
4.a fraction.

Option 2 - Irrational              

Step-by-step explanation:

To find :  The sum or product of a non-zero rational number and an irrational number is always  

Solution :

By the statement,

→ "The sum of a rational number and an irrational number is irrational."

Example : Let a rational number 3 and irrational number

Sum of rational and irrational number

5.236067977.... is a irrational number as if you add a non-repeating and non-terminating decimal to a repeating decimal, you will have a repeating decimal.

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

Example : Let a rational number 3 and irrational number

Sum of rational and irrational number

6.708203931...... is a irrational number as If you multiply any irrational number by the rational number it gives you irrational except zero which is rational.

Therefore, Option 2 is correct.

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