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.

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
Square root of 10 is irrational.
No, it is neither rational nor irrational. It is a complex number.
Oh, dude, negative square roots are actually considered irrational numbers. I know, right? It's like, they're not rational because they can't be expressed as a simple fraction. So yeah, negative square roots are definitely in the irrational club. Cool, right?
