Answer 1

A rational number is any number that can be expressed as the quotient of two integers (a fraction). Let's analyze each of the options:

1. 12⋅5.3420941... - This is a product of a rational number (12) and an irrational number (5.3420941... is non-repeating and non-terminating), resulting in an irrational number.

2. 12⋅π - This is a product of a rational number (12) and an irrational number (π), resulting in an irrational number.

3. 8⋅√25 - The square root of 25 is 5 (which is a rational number). Thus, this is the product of two rational numbers (8 and 5), resulting in a rational number.

4. 10⋅√8 - The square root of 8 can be expressed as 2√2 (which is irrational). Thus, this is a product of a rational number (10) and an irrational number (2√2), resulting in an irrational number.

Based on this analysis, the only product that is rational is:

8⋅√25
