If I have the equation 10=Log to the base of 10 of X, how do I find X?
>Hey guys I want to know how to solve this logarithm equation

you're cool

[math] 10 = log_{10} ( X ) [/math]
becomes
[math] 10^X = 10 [/math]

Thanks, anon. How is your Algebra II class going?

School is hard, isnt it? xD

Well, don't worry. Summer is just another ten months away!
You exponentiate using the base. This works because the function "log_a" is the inverse of the function "a^()"

actually [math] X = 10^{10}[/math]

No problem. It's also helpful to know this identity:
[math]\displaystyle log_a(x)=\frac{ln(x)}{ln(a)}[/math]
where "ln" is the natural log, or "log base e"
