Question

True or False: Lynn said that all square roots are irrational numbers. but are they really?
Explain your answer.

Answer 1

False. Not all square roots are irrational numbers. A square root is considered irrational if it cannot be expressed as a fraction or a decimal that terminates or repeats. For example, the square root of 4 is 2, which is a rational number because it can be expressed as a fraction (2/1) or a terminating decimal (2.0). However, the square root of 2 is an irrational number because it cannot be expressed as a fraction and its decimal representation goes on infinitely without repeating. Therefore, Lynn's statement is incorrect.
