Solution Steps

Step 1: Understanding Exact vs. Inexact Numbers

Exact numbers are those that are counted or defined, such as the number of objects or units in a set. Inexact numbers, on the other hand, are typically measurements that involve some degree of uncertainty.

Step 2: Analyzing Each Option
  • 10 dogs: This is a count of objects, making it an exact number.
  • 25 atoms: This is also a count of objects, making it an exact number.
  • 50 meters: This is a measurement, which can have uncertainty, making it an inexact number.
  • 1 dozen eggs: This is a defined quantity (12 eggs), making it an exact number.
  • 3 rulers: This is a count of objects, making it an exact number.

Final Answer

The inexact number is the measurement, which is:

\(\boxed{50 \text{ meters}}\)
