2the square root of 2. 12the square root of 2. 2the square root of 5. 12the square root of 5.

Answer 5

its multiple choice

Answer 6

you don't round, you need exact, also, @Catlover5925 please read http://openstudy.com/code-of-conduct

Answer 7

anyways, @josh543 , can you factor 180?

Answer 8

2*90

Answer 9

You asked this exact same question and I responded to it. I guess you just ignored my help. That's cool.

Answer 10

no

Answer 11

That's what he did to my response as well.

Answer 12

im just not focused

Answer 13

Seems like this user asks for help and reposts to find an answer.

Answer 14

ok, 2*90 is 180. so can you factor 90?

Answer 15

*303

Answer 16

3*30

Answer 17

ok, so now factor 30

Answer 18

3*10

Answer 19

=2*3*3*10
=2*3*3*2*5
Is this correct? Do you follow?

Answer 22

wat shood i do with that

Answer 23

1, when I ask if you understand please answer. 2, that is called a prime factorization, it is the easiest way to determine a square root.

Answer 24

so again, do you understand?

Answer 25

no

Answer 26

which part?

Answer 27

after doing the factors whats next

Answer 28

if you don't understand the factoring we cannot continue, it is a vital concept.

Answer 29

i already did the factors but what should i do with them

Answer 30

but you just said you don't understand what we have done? If you understand, please find the prime factorization of 125.

Answer 31

oh, and don't forget to show all of your work in finding that factorization

Answer 32

ok

Answer 33

Answer 34

Good job.

Answer 35
