I need help with the following:
1/4 log_2 sqrt (2)
log_2 (2) =1
therefore log_2 sqrt(2) =1/2
therefore the answer=1/8.
NB. We dont normally do homework so try the other one yourself by solving the simple quadratic.
This wasn't homework....so be sure you know what you are saying before you say it. BTW where is the 1/4 and how is it used? So don't get to fast with accusations.

Hi Lupita,
Fresco was expressing a frustration that many of us have. People coming here for homework doesn't help anyone. It might help if you gave some context to your question-- but don't overreact to his comment.
It helps to understand logarithms... they are the opposite of exponents.
This means that if
A ^ B = C
then logA(C) = B
In the problem gave...
2 ^ (1/2) = sqrt(2)
So log2(sqrt(2)) = (1/2)
Then fresco just multiplied this by the 1/4 you gave us.
----------
BTW I am a bit curious, if this is not homework, what are you using it for?
I am a pilot and use log for various things and just was experimenting with some stuff and ran into a problem. Call it a hobby.
