<p>Can anyone help me out with this math problem? I keep getting stuck.
3 to the x + 3 to the -x =10/3 ( sorry my keyboard isnt working correctly so I can´t really write it up as it should be).</p>
<p>anyone? I really ned the help, my test is in like two days, I'm freaking out that I can't solve such a simple looking problem)</p>
<p>i can't really tell what you mean...i know you mean exponents, but...</p>
<p>you should try logs. sorry i can't help much!</p>
<p>are u saying..... 3^((x+3)^-x)=10/3 ?</p>
<p>that i have no idea of. :p</p>
<p>its supposed to be ( got this damn keyboard to work):
(3^x)+(3^-x)=10/3 thanx</p>
<p>um...i used log and i keep getting no solution....which is weird....you know, when you log everything, you carry the exponents to the front, and it cancels it self out...eh i hate math</p>
<p>I graphed it and got</p>
<p>x1=-1 and x2=1</p>
<p>but to use logs wouldn't I have to simplify the whole thing to get it to just one component to the x, then I would be able to use the log right? Thats my problem, I keep getting stuck trying to simplify it (I missed the class on logs so I'm basically trying to work my way through the lesson right now)</p>
<p>I see scarlet, but how can I work it out without graphing it?</p>
<p>as far as i know, you can log the whole thing...the 1st term and the second term....well don't trust me on this, please...</p>
<p>I'd have to check up on my logs and lns, its been awhile. But if you're allowed a GDC it would be easier to do it on one, less chance of messing up.</p>
<p>ok, danke schön ( lol, I'm learning german. I should actually be studying right now I have a test in like 2 hours)</p>
<p>Haha, kein problem. viel glück!</p>
<p>whoo you german-speaking people....isn't it hard?</p>
<p>not so much. (stupid 60 second rule)</p>
<p>sometimes I have a hard time with the gender of objects etc. ( der kopf, der kopf, goddammit I need to find some logic in this to be able to remember it) But I definitely think its way harder than learning english ( my native language is spanish).</p>
<p>Gender and the cases can be quite confusing. But be glad there are only three. A good friend of mine is Polish and they have 7.</p>
<p>Yeah, my german teacher always brings up (whenever I complain about genders and cases) how the finnish have like 17 ( I'm making up the number, I dont remember exactly, but I do remeber it was a huge number)</p>
<p>There are a lot of languages that are terrible like that. I guess ones where you need to be a native speaker to understand. I couldn't imagine 7 or more cases.</p>
