Simplifying square root numbers?
If the number under the radical sign has a factor which is a square number greater than 1, then the square root of that number can be taken outside the radical.For example,sqrt(75) = sqrt(25*3) = sqrt(25)*sqrt(3) = 5*sqrt(3).
How can you tell by looking at the prime factors of 17640 that the square root of 17640 is not a whole number?
Write the prime factors as powers. In a square number, each prime number appears an even number of times - i.e., an even power. Examples: 4 = 22 (even power, this is a square) 144 = 24 x 32 (all powers are even, this is a square) 12 = 22 x 3 or 22 x 31 (3 has an odd power so it is not a square) (If a number is a perfect square, that is equivalent to saying that its square root is a whole number.) * * * * * In this case there is a particularly fast method. The number ends in 0 so 10 must be a factor of the number. That is to say, 2 and 5 must be prime factors of the number. If it is a square then 22 and 52 must be factors of the number ie 22 x 52 = 100 must be a factor. But if 100 is a factor, the number must end in 00. It does not so it cannot be a square.
What is a number called that has an odd number of factor pairs?
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.

How do you know if a number is square number?
I'm assuming you're wondering if a number is a perfect square? Well, memorization will help as will guess and check. However, if you feel like doing it all by hand, simplifying the square will help you determine if it is a perfect square. Example: let's figure out if the number 225 is a perfect square. Let's take 225 and factor it. When you factor this number, you want to look at factoring numbers which are a perfect square in and of themselves. So 22 is 4, but that doesn't factor, how about 52 ? 25 will indeed factor, so we have 25*9 (look at that, 9 is also a factor). If we split it up like this, we have sqrt(25*9). We can take the square root of these individually and multiply them together. sqrt(25)*sqrt(9) = 5*3 = 15. Therefore 225 is a perfect square of 15.

How do you factor the square root of -108?
Before you try to factor that number, you have a couple of insurmountableproblems just finding it.-- there is no such thing as the square root of a negative number, unlessyou know how to work with 'i', the unit 'imaginary' number;-- 108 is not a perfect square number, so it's not even possible to write itsexact square root.About the best you can do is:(6 i) x sqrt(3)
