Question

The square root of a rational number is also a rational number.

• A. True
• B. False

Answer 1

The correct option is B

False

Square roots of negative rational numbers are not rational as the idea of the square root exists only for positive numbers. Hence, it is not always true that square root of a rational number is also a rational number and also 2 and 3 are rational numbers but the square root of 2 and the square root of 3 are irrational numbers.
