ln x = "10 to which power gives you x?"

So basically
10^(0.513/3) = x

Because 3 ln x = 0.513
So ln x = 0.513 / 3
Then 10 to that power = x

So if I were to give you ln 100
It would be "10, to which power, gives you 100?"
And that's 10, so the answer is 10

Your only responses will be the ANSWER and some of those ass wads laughing at you cause you're not in as high of an advanced math class as them

So same thing

ln x = -0.513 / 3
e, to what power, gives you x?
-0.513 / 3.

So x = e^(-0.513/3)
Then you solve that

Always think of it like that
"The base, to which power, gives you the number you're looking for?"

Its technically a kids game but you have a lot of old lmaders
And old lmaders = the guys who have been through all this stuff
So its a good place to get actual responses rather than a textbook that is all gibberish

You'd be surprised how old some people are on these forums.

@DX.
Thanks.
I'm freaking out about finals tomorrow, I'll be lucky to finish this work and get 3 or 4 hours of sleep at most.

My school's gone insane
It used to be you had three weeks of exam time so you could study
Then they switched it to one week
And now its like two days and you have 2 - 3 exams in a day and it starts the day you're out so you get as little studying time as possible

i can help you, free

say you have 4 to the x power equals 84

use the change of base formula to obtain

4 to the 84 power equals x

now do log84

divided by

log4

and get your answer :)

3 lnx = 0 - 5.13

First what you do is you move the 3 in the beginning of the ln to the exponent of the x.

So

lnx^3 = 0 - 5.13

Now you have to cancel the Ln on the left of the equation. Ln always has an e to the bottom. Therefore multiple ln by e.

Ln cancels out and you should have

x^3 = ln-5.13

Now you get the cube root of ln-5.13

So x = Cube root of ln-5.13

You can't have a negative in a root, therefore you make an imaginary number.

Your math teacher was dumb to put decimals in a logarithm but wutev. You get the square root of either that or you get two numbers which make up that root and put the bigger numer outside.

Another way to do it is to multiply it by 1/3 and add an imaginary.

So your answer should be

x = ln[Number here][Imaginary]
OR
x = ln[Number here + Imaginary] [Root]

Hope i helped.

We had 2 days, but I was gone ALL of yesterday building a clothing shelter as my church.
So I'm trying to cram it all in today, I have Math, English, and Computer Finals tomorrow.
I'm prepared for it all excluding Math.
