An irrational number is has infinite decimal places. Adding a terminating decimal to it will not make it rational.

anonymous · Answer

so its because the product is always repeating or terminating decimal?

hero · Answer

$\sqrt{2} = 1.414213562373095048801688724209698078569671875376948073176679...$

Add .5 to that and you will get

$1.914213562373095048801688724209698078569671875376948073176679...$

As you can see, the sum is still irrational.
