There are an infinite number of irrational numbers. Here are some: e (the base for natural logarithms), pi, sqrt(2), sqrt(3), sqrt(5), square root of any number that is not a perfect square: perfect squares are 12 22 32 42 52 etc. which equals 1 4 9 16 25 ..... natural logarithm of any rational number (greater than zero) will be irrational. but not 1, since ln(1) = 0, which is not irrational. Note the logarithm of a negative number is a complex number, and the logarithm of zero is negative infinity.

The natural logarithm (ln) is used when you have log base e

The logarithm of 1 to the base 1 is indeterminate. The logarithm of a number x to the base a is a number y, such that ay = x. The most common base a is 10, or the natural base a is e (2.718281828...). It is invalid to think of logarithms base 1, because 1 to the power of anything is still 1.

The logarithm of 1.5 is approximately 0.1760912591... Your logarithm is base 10, and the natural logarithm of 1.5 (base e), is approximately 0.4054651081... Example base: 8 Approximately: 0.1949875002...

The natural logarithm is calculated to base e, where e is Euler's constant. For any number, x loge(x) = log10(x)/log10(e)

ln x is the natural logarithm of x, that is the logarithm to base e where e is euler's number (an irrational number that starts 2.71828...). If y = ln x then x = ey

The "base of the natural logarithm" is the number known as "e". It is approximately 2.718.

Rational.

A logarithm is the exponent to which a number called a base is raised to become a different specific number. A common logarithm uses 10 as the base and a natural logarithm uses the number e (approximately 2.71828) as the base.

That is a logarithm to the base "e", where "e" is a number that is approximately 2.718.

A "natural logarithm" is a logarithm to the base e, notto the base 10. Base 10 is sometimes called "common logarithm". The number e is approximately 2.71828.

"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)
