Yes. Irrational numbers are found by getting the square root of a negative number.

5*5 = 25 so one square root of 25 is 5 = 5/1 which is rational. The other square root is -5 which, since it is equal to -5/1 is also rational.

yes, one such is the square root of four, which is two

The square root of 1/16 is 1/4, so yes it's rational.

There are two answers 1 and 64

Yes.

The square root of 40 is an irrational number, due to the fact that one could extend the answer to an infinite number of decimal places if one was able to.

How about 16 as one example

Yes, they are rational.

Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.square root of -81 = square root of 81 times i = 9i

no: the decimal is not repeating or terminating and therefore cannot be written as a fraction, which is one of the two requirements to be a rational number.

No.

In general, not usually.The square root of an irrational number is always irrational.The square root of a rational number is usually irrational, but not always. You can tell by this test:If both the numerator and denominator of the number expressed as a simplified fraction are perfect square numbers (a number whose square root is a whole number), then the square root of the whole fraction will be rational.Example: Sqrt(4) =2 (the positive one). Sqrt(1) = 1. Both are perfect squares.So sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2. Another one: sqrt(4/9) = 2/3.

no square root of 9 is 3 which is rational -- to be more specific: an irrational number is a number that cannot be expressed as a fraction. Pi, for example, is one of these numbers. If a number is not a perfect square (4, 16, 9, 144, 225, etc.), then it's square root is likely to be an irrational number. For example, the square root of 2 (1.41421356...) is an irrational number because it cannot accurately be expressed as a fraction.

Raising to the one half (1/2) power is the same as taking the square root.
