The square root of 4 is 2 which is a rational number and also a prime number
It is rational.
It is rational. It is rational. It is rational. It is rational.
-1,0,or 1 the negative square root of four is negative two and the square root of four is two
Yes, because when x equals 1, the square root of x is rational and the square root of -x is irrational, and when x equals -1, the square root of x is irrational and the square root of -x is rational.
The square root of 4 is 2 which is a rational number and also a prime number
Yes. So is the positive one.
rational
It is rational.
If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.
It is rational. It is rational. It is rational. It is rational.
The negative square root of 16 is -4. It can be written as the ratio of 792 to -198, so it's rational.
-1,0,or 1 the negative square root of four is negative two and the square root of four is two
Yes it is.
No.
Yes, because when x equals 1, the square root of x is rational and the square root of -x is irrational, and when x equals -1, the square root of x is irrational and the square root of -x is 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
