200 100,2 50,2,2 25,2,2,2 5,5,2,2,2 2 x 2 x 2 x 5 x 5 = 200 The square root is 10 times the square root of 2.
you call it a square root. that's so corny but true.

First, pick a factor pair whose product is 246. Then, for each number that is not prime, choose a factor pair for it. Continue until you have reduced each branch of the tree to prime numbers. Here is a factor tree OS 246, using periods for spacing: ....246 ...../ \ ...6 x 41 ../ \ 2 x 3 The prime factors are 2, 3, and 41.
The square root of 64.36 is an irrational number. Consequently you cannot find the root using a factor tree.
The square root of 900 is 30 and it is a factor of 900
200 100,2 50,2,2 25,2,2,2 5,5,2,2,2 2 x 2 x 2 x 5 x 5 = 200 The square root is 10 times the square root of 2.
147 49,3 7,7,3 The square root of 147 equals the square root of 49 times the square root of 3 which is 7 times the square root of 3.
A factor tree gives you the prime factorization of a number. If that number is a perfect square, the prime factors will be in pairs. Select one of each pair. Example: 2 x 2 x 3 x 3 = 36 2 x 3 = 6, the square root of 36

A factor tree has factors, not square roots - unless they are integers.
