검증된 단계별 안내

Step 1: Understand the concept of measured numbers. Measured numbers are obtained through measurement and have a degree of uncertainty. They are different from exact numbers, which are counted or defined and have no uncertainty.
Step 2: Analyze the given pair of numbers: '1 table' and '4 chairs'. Determine whether these numbers are measured or exact.
Step 3: Recognize that '1 table' is a counted quantity. Counted quantities are exact numbers because they are determined by counting and do not involve measurement uncertainty.
Step 4: Similarly, recognize that '4 chairs' is also a counted quantity. Like '1 table,' it is an exact number because it is determined by counting and does not involve measurement uncertainty.
Step 5: Conclude that there are no measured numbers in this pair of numbers. Both '1 table' and '4 chairs' are exact numbers.
