4 rational because 4 times 4 is 16 and there is nothing to start a pattern, its a plain number so its rational, irrational would be a number with no pattern like 18.86743038434953949345..., another rational is like 18.3333333... or 18.123123123123123123123123123..., or 95.8989898989898989..., because they have patterns.

4.6 is rational.
-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.

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.
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 -81 is an imaginary number, specifically 9i, where i represents the imaginary unit equal to the square root of -1. Since the square root of -81 does not result in a real number, it is considered irrational. Rational numbers are those that can be expressed as a ratio of two integers, whereas irrational numbers cannot be expressed in this form.
Square root of 10 is irrational.
