Answer 2

The expression "3,4(56)" does not represent a valid mathematical notation for a number. It appears to be a combination of a decimal point (".") and parentheses. In standard mathematical notation, parentheses are typically used for grouping or indicating repeating patterns in decimal representations.

If you meant to write "3.456" instead, then yes, 3.456 is a rational number. A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero. In this case, 3.456 can be written as the fraction 3456/1000, which simplifies to 27/25. Therefore, 3.456 is a rational number.
