Final answer:
Among the options given, √100 is a rational number because the square root of 100 is 10, which is a whole number and can be expressed as a fraction (10/1).
Step-by-step explanation:
The question you've asked pertains to identifying which of the given options is a rational number. A rational number is any number that can be expressed as a fraction or quotient of integers, where the denominator is not zero. Rational numbers include integers, fractions, and finite decimals.
Now, to determine which of the following is a rational number:
- A) √10
- B) √100
- C) √1,000
- D) √100,000
Among these options, √100 is a rational number. When we apply the square root to 100, we get 10, which is a whole number and certainly can be expressed as a fraction (10/1). The other options do not simplify to whole numbers in their square root forms and thus are not immediately recognizable as rational.
