Question

Frankie argues that the fraction 20 is a rational number because the square root of 20 is 10. Frankie believes that because 10 is a whole number, it is rational

Alejandro disagrees. He believes that 20 is a rational number because the square root falls between 4 and 5, and the decimal terminates.
statement RFST describes who is correct?

The square root of 20 is √(2 * 2 * 5) which is 2√5 Not so

√5 does not terminate and there is no pattern to the decimal. √5 is irrational.

Neither one is correct.
