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
The square root of 1 is 1 which is a rational number
The square root of 100 is 10, and it is a rational number.
No.
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. 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, 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
yes, one such is the square root of four, which is two
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.
