I need help with logs. Anyone good at math who can help me?

Heather is a math major..she may be able to help

Definitely Heather for sure, but what's da prob u got with logs?

Yeah, I know Heather is a teacher and all, but she ain't around.

 

I need help with stuff like this, but ya can't use a calculator (answers can contain logs it says):

Sorry man, I think that's our next chapter in Analysis. I can bore you to death with inverse trig functions though: cos^-1(cos(3/5)) ...that's an easy one. Right now we are covering periods and sinusodial waves.

well logs are base 10 so you can take 10^(log (log(x-15))=10^0

 

and for the other problem sum of logs is same as multiplication inside so log (2x-9) + log (3x-1) = log ((2x-9)(3x-1))

 

i hope this helps and is correct

I mite be able to help ya out, lemme go find my maths book.

damn...I haven't taken a math course since my freshman year of college. I'm much happier with social sciences.

It's Log, It's Log, it's big, it's heavy, it's wood. It's Log, it's Log, it's better than bad, it's good, it's better than bad, it's good.

 

Does that help any??

I'm pretty good at math. Log's are calculus right? I may not remember all of it but I did pretty decent in the class.

 

Whats the specific question?

What your gonna want to do is clear the log log in the first part. I have no idea what log times log is but I'm assuming thats somewhere in your book (I only remember the processes, everything else is very fuzzy). That may work out to an even number and then you'd just do the x-15 to work it to zero. In this instance I think x just has to be 15.

Ah crap...if I had an example problem with the solution I could do more, but now I'm confusing my self, lol.

 

I should know this, but alas, how quickly I forget what i learn.

Just do log 10 so it cancels out to 1, and then find x from the brackets.

I hate math infact the only way for me to have a %10 chance of passing is to do every HW since my test avg is 30
