The square root of 900 is 30 and it is a factor of 900
The idea is to take out perfect squares. The largest perfect square in this case is 256, which is the square of 16 (if you have trouble figuring this out, you can take out a smaller perfect square first, and then see if you find additional perfect squares). In any case, the end result should not have a factor that is a perfect square. Using the symbol "root()" for square root: root(512) = root(256 x 2) = root(256) x root(2) = 16 root(2)
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
Find the square root of each of its components, and muliply them together. For example, 36x8 the square root of 36 is 6 the square root of x8 is x4 so the square root of 36x8 is 6x4
You use the pythagorean theorem.
Use a calculator. Most will allow you to find 70(1/4) Or find the square root of the square root of 70.
The square root of 64.36 is an irrational number. Consequently you cannot find the root using a factor tree.
factor it
Square Root
If 440 is the area, find the square root. > 20.976
You first find a factor of 125 that is also a perfect square. It is 25. Then, write 125 as 5(25). Then, square root the 25, and therefore your answer is 5*sqrt5.
to find the Pythagoras Theorem
The square root of 20 is an irrational number that can be expressed as 2 times square root of 5
It is 25 because 25*25 = 625

There are different answers for different expressions but essentially, you can either evaluate the expression and then find the square root using a calculator, computer or numerical methods, or you can work out the square root algebraically.
Math.sqrt(number) function is used to find the square root of a number.. try it
using calculator , it will be equal to11.44
