Definition of Natural Numbers: Natural numbers are the set of positive integers starting from 1. They do not include fractions, irrational numbers, or negative numbers. Let's evaluate each choice to see which one is a natural number.
Evaluate Choice (A): Choice (A) is Ο (pi), which is an irrational number. It is not a natural number because it cannot be expressed as a positive integer.
Evaluate Choice (B): Choice (B) is β2, which is a negative integer. Negative integers are not considered natural numbers.
Evaluate Choice (C): Choice (C) is 5, which is a positive integer. Positive integers are natural numbers.
Evaluate Choice (D): Choice (D) is the square root of 7 (7β), which is an irrational number. It is not a natural number because it cannot be expressed as a positive integer.
