Geom Notes For SQUARE ROOTS! ;]

Roots
Square Roots
When working a square root problem. Ask: -- what times itself is the number inside the root symbol?”
=3 because 3 times 3 is 9
because 5 times 5 is 25
Roots and Prime Numbers
=3 because 3x3x3 is 27. The small 3 outside the root symbol tells how many times the answer must be multiplied to get the number inside the root.
because 2x2x2x2x2 or 25=32
Prime Number: a number with only factor one and itself 2,3,5,7,9,11,13,1,7,19,23… are prime numbers fifteen is not prime because 3 and 5 also divide it evenly. 15 is a composite number.
Prime factorization.
Prime Factorization is writing a number using multiplication of only prime numbers.
12 can be written as 3x4 but 4 is not prime and can be written as 2x2
So the prime factorization of 12 is 3x2x2 this can also be written 3x22
Graphing Prime Numbers

330

10 x 33
5 x2 3 x 11
To write 330 using its prime factorization start breaking it down by each number.
