whats the question
OpenStudy (anonymous):
simplify?
OpenStudy (sugarapples):
yes
OpenStudy (anonymous):
what are some factors of 1000?
OpenStudy (anonymous):
what is the largest factor?

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)

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

@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 $$30\sqrt{10}$$

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

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 $$30*\sqrt{10}$$
