Solution

To get the product as irrational, the numbers need to have their rational and irrational parts different such that their product too has an irrational part.
The given pair of numbers are 3+32 and 23.
Multiplying these 2 numbers we get,
=(3+32)×(23)
=3×(23)+32×(23)
=3233+636
It is an irrational number.
