To determine the type of number that results from the operation \(3.4059... - \frac{8}{5}\):
-
Identify the nature of the numbers involved:
- \(3.4059...\) is a decimal that appears to be non-terminating and non-repeating, which means it is an irrational number. However, it may also just be a rounded form of a rational number if it actually represents a repeating decimal (e.g., if it were \(3.405909090...\)). But without more context, we will consider this to be an irrational number.
- \(\frac{8}{5}\) is a fraction and is a rational number.
-
Subtract the numbers:
- When you subtract a rational number (\(\frac{8}{5}\)) from an irrational number (\(3.4059...\)), the result will be irrational.
-
Conclusion: Subtracting a rational number from an irrational number results in an irrational number.
Therefore, the correct response is: Irrational, because one number is irrational.
