3 is a factor of the square number 9.
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).
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.
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
what multiplying factor decrease a number by 3 %
Any number that is a multiple of 3 has 3 as a factor.

A factor that is a square number. 16 is a square factor of 32.
Based on your description, it could be 9,4, or 1.
Since 440 is not a square number, it can't be a square factor.
There are two solutions to the question:- 2 & 3 2 is the square root of 4 - and a factor of 4 (and 8) 3 is the square root of 9 - and is also a factor of 9
4 is the only square number that is a factor of 84. No square number is a factor of 105.
We need to know what number the square is a factor of.
9 is a square number and is a factor of 63
It is the square of any one of the four multiples of 6 between 10 and 31.
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)
