Number 18 first of all is not a square number, meaning you cannot get 18 by squaring any whole number. That means that it's square root is also not a whole number. So the simplest and most convenient way of expressing the square root of 18 is 3√2..
Correspondingly, how do you find the square root of 18?
Remember the perfect squares between which the given number whose square root has to be found lies. So, Sqrt of 18 = Sqrt of 16 + b/a = 4 + 2/9 is nearly equal to 4 + 2/10 = 4 + 0.2 = 4.2 is the square root.
Also, what is the value of Root 18? Square root number table

People also ask, does 18 have a square root?
So, because 18 is between 16 and 25, we know its square root must be between their square roots, that is, between 4 and 5. It should be closer to 4 because 18 is closer to 16.
Is 18 a perfect square?
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 18 is about 4.243. Thus, the square root of 18 is not an integer, and therefore 18 is not a square number.
