It is neither, it is an imaginary number.
The negative square of 36 is -(36*36) = -1296. It is rational.
It is neither because the square root of -18 is an imaginary number but the square root of 18 is irrational
The square root of 1.44 is 1.2 which is a rational number
It is a rational number because it can be expressed as an improper fraction in the form of -80/1
No, it is neither rational nor irrational. It is a complex number.
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
Neither. (It is a complex number.)
No it is not. It is not irrational either but is an "imaginary" number.
It is all of them except for irrational.
It is irrational.
-4.9 is a rational number. If a number is irrational, then it can not be expressed as a finite number of digits. A few examples of irrational numbers are: pi, the square root of any integer which is not square and the golden ratio (phi).
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.
