Q. Is the following number rational or irrational?\newline50\sqrt{50}\newlineChoose 11 answer:\newline(A) Rational\newline(B) Irrational
  1. Evaluate square root of 5050: Evaluate the square root of 5050. \newline50\sqrt{50}\newline= 25×2\sqrt{25 \times 2}\newline= 25\sqrt{25} ×\times 2\sqrt{2}\newline= 5×25 \times \sqrt{2}
  2. Identify irrationality of 2\sqrt{2}: Identify whether 2\sqrt{2} is a rational or irrational number.2\sqrt{2} is known to be an irrational number because it cannot be expressed as a fraction of two integers.
  3. Determine nature of product: Determine the nature of the product of a rational number 55 and an irrational number 2\sqrt{2}.\newlineThe product of a non-zero rational number and an irrational number is always irrational.
  4. Conclude rationality of 50\sqrt{50}: Conclude whether 50\sqrt{50} is rational or irrational.\newlineSince 50\sqrt{50} is equal to 5×25 \times \sqrt{2}, and we have established that 2\sqrt{2} is irrational, 50\sqrt{50} must also be irrational.
