Yes. For example, the square root of 1/9.
Neither; it is a non-repeating, non-terminating decimal - it is an irrational value.
Yes, because 0.44444.. is 4/9 and sqrt is 2/3 = .6666666...
The 8th root
The principal square root is the non-negative square root.
Yes. For example, the square root of 1/9.
Neither because the square root of 400 is 20
A square root
The square root of 100 is 10, which is rational. If you must have it in the form of a repeating decimal, you can try either 10.0... or 9.99... which, mathematically, is the same.
No, it is neither.
No, it is neither.
Not really, 10² = 100
The answer is yes given no restrictions on the kinds of numbers we allow to be discussed. Simply, think of a repeating decimal number. It has a square root and therefore it is a square. That square root is likely to be an irrational number, but it is a number and so it's square exists and that square is a repeating decimal number. For example, 1/9 (one ninth) is 0.111111... and it is the square of 1/3 (a third), 0.333333...
Neither; it is a non-repeating, non-terminating decimal - it is an irrational value.
Yes the square root of 150 is 12.247448713915890490986420373529This is irrational because the answer is a number that the decimal goes on forever without repeating.
approximately .66 repeating
Square root of 2...
