Radicals

divisibility and factors
1. to find out if a number is divisible by 3 just add all the numbers and then see if that number is divisible by 3
  1. example; 319 you would add 3+1+9=13 319 is not divisible by 3 because 13 cant be divided by 3
  2. 319 is not divisible by 3 because 3+1+9=13 and 13 is not divisible by 3
factors and factorization
1. factors are the number that a certain number is divisible by.
2. you could also solve these problems by doing factor trees
The greatest common factor (GCF) is the the biggest number that 2 certain numbers are divisible by
1. Example: 20 and 10
  1. 20: 1,2,4,5,10,20
    1. 10:: 1,2,5,10
      1. The GCF is 10
Simplifying radicals
1. You need to find a pair a numbers that will multily to equal it. Then make sure that at least one of the numbers is a perfect square.
Adding and subtracting radicals
1. You just add the square roots unless they're not the same. Then you have to go through the process of simplifying.
2. 3 square root of 3 - square root of 27
  1. 3 square root of 3 minus square root of 9 x 3
    1. 3 square root - three square root of three
      1. Equals 0
multiplying radicals
1. When multiplying radicals, you must multiply the numbers OUTSIDE the radicals and then multiply the numbers INSIDE the radicals.
