Q. Which of the following are irrational numbers?Multi-select Choices:(A) (B) (C) (D)
- Define Irrational Numbers: Understand the definition of irrational numbers. Irrational numbers are numbers that cannot be expressed as a simple fraction, meaning their decimal form is non-repeating and infinite.
- Evaluate : Evaluate each choice.(A) - The square root of cannot be expressed as a simple fraction, and its decimal form is non-repeating and infinite.
- Check Choice (B): Check the next choice.(B) - This is an integer and can be expressed as a fraction (), so it is not irrational.
- Evaluate Choice (C): Evaluate choice (C).(C) - Zero is a whole number and can be expressed as a fraction , so it is not irrational.
- Look at Choice (D): Look at choice (D).
(D) - Pi is well-known as an irrational number because it cannot be expressed as a simple fraction and its decimal expansion is non-repeating and infinite.
