Question

10^2x = 500

Answer 1

Don't natural log, take the base ten log

Answer 2

2x=log 500

Answer 3

btw, I'm assuming you mean 10^(2x)

Answer 4

Yes, that's what I was thinking, but I wasn't positive that was going to work. Okay, thanks guys!

Answer 5

Wait, so log and ln are essentially the same thing?

Answer 6

No...

Answer 7

say you have a number 10^x

Answer 8

taking the log of that means you take the base 10 logarithm, which yields x

Answer 9

Say you have a number e^x

Answer 10

taking the natural log of that yields x

Answer 11

If you take the ln of 10^x, you'll get a completely different number

Answer 12

And, to be honest, it's been so long since I've learned about logs that I've forgotten, but I could look it up.

Answer 13

Woops sorry yeah I'm wrong. Havent used log in a while and I tend to use e and natural log because I'm use to dealing with real life applications.

Answer 14

@inkyvoyd Is correct

Answer 15

Basically the log is like this
If you have a log base x of y, you are asking this:
x to the power of what = y?
Where what is the result when you take the log

Answer 16

Ah, I never enjoyed logs...thank you though. I think I understood that. Hopefully...

Answer 17

Well, to be honest, I cheated on much of my logs during algebra two, and I'm only regretting it :S

Answer 18

Haha, I never even took algebra two, so I'm struggling with this quite a bit in my precal class! It doesn't seem like it's that hard, but I guess there's always a problem when you try to run before walking :P
