Usually, but not necessarily.
A logarithm that is not an integer-value is irrational. For example log10100 = 2 which is a rational number. log1012 = 1.0791812460476... which is an irrational number.

What irrational number is the base of a natural logarithm?
The number is called e, and it is approximately equal to 2.718.
What is a list of irrational number?
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.
Is logarithm numbers irrational?
Usually it is, yes. Of course, in some special cases the result of taking a logarithm is rational - such as taking the base-10 logarithm of 100.
Why does pi go on forever?
Because it's an irrational number, and that's what "irrational" means. There are lots of other irrational numbers, like the base of the natural logarithm e or the square root of 2.In fact, there are more irrational numbers than rational numbers. A lot more.Infinitely more, even. There are an infinite number of rational numbers, but the infinite number of irrational numbers is a higher infinity than the infinity of rational numbers.
What is the sum of an rational number and irrational number?
An irrational number.
Is the base 2 logarithm of 32 a rational number or an irrational number?
Rational.
What irrational number is the base of a natural logarithm?
The number is called e, and it is approximately equal to 2.718.
What does In x equal?
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

What are the examples of irrational numbers?
The square root of any number which is not a perfect square;The cube root of any number which is not a perfect cube;Pi, the circular constant.e, the natural logarithm base number.

What is the difference between the common logarithm and the natural logarithm?
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.
What does ln stand for in the Steinhart hart equation?
"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 is a natural logarithm?
That is a logarithm to the base "e", where "e" is a number that is approximately 2.718.
What are some examples of irrational numbers?
Pi (used to calculate the circumference and area of a circle) Phi (the so-called 'golden ratio', and its inverse) e (the base of the natural logarithm) the square roots of 2 and 5
What is an antilogarithm?
An antilogarithm is the number of which the given number is the logarithm (to a given base). If x is the logarithm of y, then y is the antilogarithm of x.
