What else can I help you with?
In simple terms please explain how to use square root keys on a calculator?
type in the number you want to find the square root of, then press the square root button. if it doesnt tell you straight away, press =. ADDED: A good tip, and one I find useful, to verify you have understood the method is to try it on a number you know. So here for example, you know the square root of 4 is 2, and the square root of 100 is 10. So if you try the method and see the right answer, as the calculator can't make mistakes but can only follow your instructions, you know you have used it correctly.
How do you find the square root of a number that isn't a square?
There are a number of ways. The simplest would be to use a calculator (you probably would not know how to use log tables or a slide rule!) You could find a square root graphically; use numerical methods such as the Newton-Raphson method (not very fast but simple). There is also a method similar to long division, but that is rather complicated.
How does finding the square root of a number compare to finding the cube root of a number?
The only significant difference that I know of is that there is a method, somewhat like long division, that can be used for finding the square root. I am not aware of a similar process for a cube root.

How will you know that the root of a given number is even or odd?
Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.
How do you know a number is a perfect square?
When it can be square rooted
If you do not know the square root of a really big number how do you know if its rational?
Assuming your number is an integer: if the number is a perfect square, the number is of course an integer, and therefore rational. If the number is NOT a perfect square, it is irrational.
What do you know about square roots?
Every square number has a square root
Can the square of an irrational number be rational?
The answer to this question confuses me. The square root of two is an irrational number, so obviously if the square root of two is squared it becomes two which is a rational number. Thinking of it that way then the answer is yes, the square of an irrational number can be a rational number. But . . . You had to know beforehand that the irrational number was the square root of another number. If you start out with an irrational number such as Pi you cannot square it because you cannot know the entire number in order to square it.
What is a shortcut for determining the surface area of a sphere if you know its volume?
multiply V by 3 then divide by 4pi , find the cube root of this, then square it and multiply by 4 pi
What do you know about square numbers?
A square number is multiplied by two of the same numbers.
What is largest perfect square factor?
We need to know what number the square is a factor of.
