Just plug it in. Where are you having troubles?
OpenStudy (anonymous):
All of it. @greenglasses

Solve:
\[\frac{ 3 }{ 19 + 2 } - \sqrt(19-3)\]
OpenStudy (anonymous):
That's what f(19) means

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

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

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.

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