a round number
If a number is 'squared' it's simply multiplied by itself. for example 3 squared is 3 x 3 which equals 9.
a squared plus b squared is c squared
Anything multiplied by itself produces a square number. It's the definition.
5 squared equals 25. This is because 5*5 = 25. The definition of squared means you are multiplying a number times itself.
No, 8 squared is not an irrational number. When you square 8, you get 64, which is a whole number and therefore a rational number. Rational numbers can be expressed as the quotient of two integers, and since 64 can be expressed as 64/1, it fits this definition.
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
It is based on definition that you have to accept...which is: i = the square root of -1 So, if you were to square i then you would get -1. Hope that helped.
Yes.
It is b*b
A number squared means that the number is multiplied by itself.
The result of a number multiplied by itself
A squared number is the product of an integer times itself. So, 16 is a squared number. 4 * 4 = 16.
