Just plug it in. Where are you having troubles?

OpenStudy (anonymous):

All of it. @greenglasses

OpenStudy (anonymous):

Solve: \[\frac{ 3 }{ 19 + 2 } - \sqrt(19-3)\]

OpenStudy (anonymous):

That's what f(19) means

OpenStudy (anonymous):

is that a test?

OpenStudy (anonymous):

No. @crazy_cat_girl And @greenglasses I got to 7\[\sqrt{16}\]

OpenStudy (anonymous):

ok |dw:1410995224266:dw|

OpenStudy (anonymous):

What do you mean by 'you got to 7 sqrt(19)?

OpenStudy (anonymous):

\[\frac{ 3 }{ 21 } which equals 7 so 7\sqrt{16}\]

OpenStudy (anonymous):

3/21 doesn't equal 7: 21/3 does, so you probably got messed up there.

OpenStudy (anonymous):

You need to do (3/21) - sqrt(16) to find the answer.

OpenStudy (anonymous):

No, I know. lol. I didn't mean that

OpenStudy (anonymous):

3? Because 3/21=7 and 16-7=3 @greenglasses

OpenStudy (anonymous):

Or -3 ? Because 7-16

OpenStudy (anonymous):

3/21 = 1/7. sqrt(16) = 4. So you need to do (1/7) - 4

OpenStudy (anonymous):

-3.857?? I'm sorry for being confused. @greenglasses

OpenStudy (anonymous):

Don't worry about that, that's what this site is for. And yes, that's what I got: it's -27/7 in fraction form.

OpenStudy (anonymous):

Well thank you! And should I put it in fraction for or decimal?

OpenStudy (anonymous):

If it doesn't specify anywhere, I'd put it in fraction form, since it's exact.

OpenStudy (anonymous):

Usually questions say 'round answers to the tenth place' or something though.

Thank you!!
