"Ln" in that equation is the "natural logarithm" of a number.
The "common logarithm" ... log(x) ... is the logarithm of 'x' to the base of 10.
The "natural logarithm" ... ln(x) ... is the logarithm of 'x' to the base of 'e'.
'e' is an irrational number, known, coincidentally, as the "base of natural logarithms".
It comes up in all kinds of places in math, physics, electricity, and engineering, especially in
situations where the speed of something depends on how far it still has to go to its destination.
'e' is roughly 2.7 1828 1828 45 90 45 ... (rounded)

What happens to the barrier potential when the temperature increases?
barrier potential P0=(kT/q)*ln(Na*Nd/Ni^2) when T ↑, P0↑.
What is loudness mesured in?
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".
How is thermodynamic probability related to entropy?
it entirely depend on what kind of a system you are working with. g is the probablity (number of accessible states) and k ln g is entropy and probablity is directly related to g
What does e stand for in chemistry in the Clausius-Clapeyron equation?
It stands for euler's number. Its a mathematical constant with the value of approximately 2.72. (Like the value of π(pi) is 3.14, the value of e is 2.72) In the Clausius-Clapeyron equation the "ln"(natural logarithm) is the inverse of "e" e^x = (y) ln(y)=x

How do you find value ln 2.33?
To find ln 2.33, you need a calculator. It is the solution of the equation e^x = 2.33. ln 2.33 = 0.84586 (using a calculator)
How do you solve this logarithmic equation ln x equals 5?
In the equation ln(x) = 5, the solution is x = (about) 148.4. To solve, simply raise e to the power of both sides and reduce... ln(x) = 5 eln(x) = e5 x = 148.4
If you have a number with the exponent x how do you find the answer?
Take the natural logarithm (ln) of both sides of the equation to cancel the exponent (e). For example, ify=Aexlog transform both sides and apply the rules of logarithms:ln(y)=ln(Aex)ln(y)=ln(A)+ln(ex)ln(y)=ln(A)+xrearrange in terms of x:x=ln(y)-ln(A), or more simplyx=ln(y/A)
What is the equation for exponential interpolation?
The correct formula for exponential interpolation is: y =ya*(yb/ya)^[(x-xa)/(xb-xa)], xa<x<xb and also, x=xa*[ln(yb)-ln(y)]/[ln(yb)-ln(ya)]+xb*[ln(y)-ln(ya)]/[ln(yb)-ln(ya)], ya<y<yb
How do you solve this logarithmic equation 3x plus 7 equals 20?
To be logarithmic the equation would be, ( otherwise just linear ) 3x + 7 = 20 subtract 7 from each side 3x = 13 now, you know the answer is between x = 2 and x = 3, so I use natural logs both sides ln(3x) = ln(13) as this is a logarithmic operation you can bring down the x in front of the ln sign on the left x ln(3) = ln(13) divideboth sides by ln(3) x = ln(13)/ln(3) ( not ln(13/3)!!!!! ) x = 2.334717519 -------------------------check in original equation 3(2.334717519) + 7 = 20 13 + 7 = 20 20 = 20 --------------checks
What does NN LN stand for in short hand rule?
yes
What is the dervative of x pwr x pwr x?
For the function: y = x^x^x (the superscript notation on this text editor does not work with double superscripts) To solve for the derivative y', implicit differentiation is needed. First, the equation must be manipulated so there are no x's raised to x's on the right side of the equation. So, both sides of the equation must be input into a natural logarithm, wherein we can use the properties of logarithms to remove the superscripted powers of the right side: ln(y) = ln(x^x^x) ln(y) = xxln(x) ln(y)/ln(x) = xx ln(ln(y)/ln(x)) = xln(x) eln(ln(y)/ln(x)) = exln(x) ln(y)/ln(x) = exln(x) ln(y) = ln(x)exln(x) Now there are no functions raised to functions (x's raised to x's). Deriving this equation yields: (1/y)(y') = ln(x)exln(x)(x(1/x) + ln(x)) + exln(x)(1/x) = ln(x)exln(x)(1 + ln(x)) + exln(x)(1/x) = exln(x)(ln(x)(1+ln(x)) + (1/x)) Solving for y' yields: y' = y[exln(x)(ln2(x) + ln(x) + (1/x))] or y = xx^x ln(y) = ln(x)x^x ln(y) = xxln(x) ln(y) = exlnxln(x) y'/y = exlnx[ln(x) + 1)ln(x) + exlnx(1/x) y' = y[exlnx(ln2(x) + ln(x) + 1/x)] y' = xx^x[exlnx(ln2(x) + ln(x) + 1/x)]
