Q. Which of the following is an irrational number?\newlineChoices:\newline(A)​π\pi\newline(B)44\newline(C)00\newline(D)55
  1. Definition of Irrational Number: An irrational number is a number that cannot be expressed as a simple fraction - that is, the decimal goes on forever without repeating. Let's evaluate each choice to determine if it is irrational.
  2. Evaluation of Choice (A): Choice (A) is π\pi. Pi (π\pi) is known to be an irrational number because it cannot be expressed as a fraction and its decimal representation is non-terminating and non-repeating.
  3. Evaluation of Choice (B): Choice (B) is 44. The number 44 is a whole number and can be expressed as a fraction (41\frac{4}{1}), so it is not an irrational number.
  4. Evaluation of Choice (C): Choice (C) is 00. The number 00 can also be expressed as a fraction (0/1)(0/1), so it is not an irrational number.
  5. Evaluation of Choice (D): Choice (D) is 55. The number 55 is another whole number and can be expressed as a fraction (51\frac{5}{1}), so it is not an irrational number.
