3√ 1000

OpenStudy (anonymous):

whats the question

OpenStudy (anonymous):

simplify?

OpenStudy (sugarapples):

yes

OpenStudy (anonymous):

what are some factors of 1000?

OpenStudy (anonymous):

what is the largest factor?

OpenStudy (anonymous):

besides 1000 itself

OpenStudy (sugarapples):

100

jimthompson5910 (jim_thompson5910):

hint: 1000 = 100*10

OpenStudy (anonymous):

well no thats not the largest below 1000, but thats perfect, thats the factor we are looking for

OpenStudy (anonymous):

ok so rewrite as 3sqrt(100 * 10)

OpenStudy (anonymous):

$$3\sqrt{100*10}$$

OpenStudy (anonymous):

because we want a factor that we can take the square root of, so thats perfect

OpenStudy (anonymous):

we can rewrite that as $$3\sqrt{100}*\sqrt{10}$$ are you ok with that rule?

OpenStudy (sugarapples):

yes so the answer would be 10

OpenStudy (anonymous):

the answer to what?

OpenStudy (anonymous):

@sugarapples what is the square root of 100?

OpenStudy (sugarapples):

10

OpenStudy (anonymous):

pefect, so now we can rewrite that as $$3*10*\sqrt{10}$$ are you ok with that?

OpenStudy (sugarapples):

yes

OpenStudy (anonymous):

ok so thats $$30\sqrt{10}$$

OpenStudy (anonymous):

now is there a factor of 10 that we can take the square root of and get an integer (whole number)?

OpenStudy (anonymous):

@sugarapples

OpenStudy (anonymous):

??

OpenStudy (sugarapples):

30

OpenStudy (anonymous):

no

OpenStudy (anonymous):

there is not a factor of 10, other than 1, that we can take the square root of and get a whole or rational number, so we are done, final answer is $$30\sqrt{10}$$

OpenStudy (sugarapples):

thank you

OpenStudy (anonymous):

yw

OpenStudy (anonymous):

i hope you understand that $$30\sqrt{10}$$ is the same as $$30*\sqrt{10}$$
