ln(x) = log10(X)/log10(e)
Stored Chemical energy being converted to, and released as Heat energy.
-- Measure the diameter of the dish, in feet.-- Take the frequency of the satellite signal, in gigahertz.-- Multiply the two numbers.-- Take the common log of the product.-- Multiply the log by 20, and then add 71/2 .-- The result is very close to the gain of the dish, in dB,when used for signals at that frequency.-- I'm sorry if you don't understand that, but it is the answer to the question.

To make a natural log a log with the base of 10, you take ten to the power of you natural log. Ex: ln15=log10ln15=log510.5640138 I'm sorry if you don't have a calculator that can do this, but this will work.
The chemical energy stored in the log is converted into heat energy.
The natural log of a number is some other number such that if you take e (2.718281828...) and raise it to that other number you would get the first number. Another way to say this is that a natural log is a log with base e. The common log of a number is some other number such that if you take 10 and raise it to that other number you would get the first number. The natural log base, e, is a special transcendental number, chosen so that the derivative (respect to x) of ex is equal to ex . In other words, the slope of a tangent line to the curve y = ex at point (x, ex) is equal to ex for all x
y = log 2x → x = 1/2 <base of log>y So: y = log102x → x = 1/210y (common logs) y = loge2x → x = 1/2ey (natural logs)

If that is the hydronium ion concentration, then -log(H+) = pH negative natural common log10 of the H+concentration. If this is the hydroxide ion concentration, there's a couple ways of going about it. You could find the pOH = -log(OH-) and subtract it from 14 Or you could solve for the hydronium ion conc. and then take the negative log of the result. Just remember p of anything (pH, pOH, pKa, etc) is just the negative natural common log of whatever number.
The natural log of 100 is about 4.605. The transcendental number e (about 2.718281828) raised to the power of 4.605 is 100.
