0.25^x = 0.05
i can't for the life of me remember how to do this...can someone enlighten me?
oh yes....solve for x
You mean, aside from using a calculator program to type in
.25 [x^y] <insert number here> <ENTER>
and figuring out that x = 2.16 something?
take logs of both sides:
x ln(0.25) = ln(0.05)
thus x = ln(0.05) / ln(0.25) = 2.16.....

Yup, swiftaw's right. This works exactly. (Sobs silently as realization kicks in that much of my high school math classes have been forgotten...)
YOU are blowing my mind here.
The question really is, why do you need to know?
Are you all THAT poor at maths?
Seriosuly, I'm in going into 9th grade and I knew how to do that and I'm not like a genious (although I do get As in math).
I AM SO GLAD I AM GOING TO ART SCHOOL!
Ok so I am working on a joke and I am totally not a joke maker, so come up with your best punch line for this.
Q: How many creatives does it take to do math?
A: It really doesn't matter... they all come up with different answers no matter how many you have.
i just couldn't remember i was supposed to log....totally forgot.
and i need it so as to solve a genetics problem
Thats a good one
Learn the laws of logs and you might not find this as difficult.
Don't think I ever knew.
interesting that even though we're all such 'computer nerds' when it comes to math, we still have such different educational backgrounds and interests
I really thought about something really crazy running in this thread, but...
Are you that poor at grammar?
Think of "maths" as the British equivalent of our American word mathematics. He didn't use bad grammer, he just lives in a different country. Ease up.
Logs - that's what you get when you cut down trees. Right?

Isn't mathematics Latin?
While there may laws of logs (I've already admitted to not being science of mathss minded) there are no laws to grammer. Don't think of grammar as laws or rules, just suggestions or guidelines.
kelsey wrote the grammer laws.
Only type of 'log' I know is the log generated by various computer programs.
Keep in mind that in the USA, we often refer to the basics of education as the 3 "Rs"
