Is a logarithm an irrational number?
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.
Is it possible for a logarithm to equal a negative number?
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
Why is log -10 display an error on the calculator?
In the real numbers, the logarithm is only defined for positive numbers. The logarithm of zero or a negative number is undefined. (For calculators who work with complex number, only the logarithm of zero is undefined.) This follows from the definition of the logarithm, as the solution of: 10x = whatever "Whatever" is the number of which you want to calculate the logarithm. Since 10x is always positive, that means you can't find an "x" such that the power results in a negative number, or in zero. The same applies if you use a base other than 10, for example the number e = 2.718...
What are some examples of logarithms?
A logarithm answers the question of how many times you must multiply a number by itself to get another number. For example, 3x3x3 is 9, so to get 9, the logarithm is 3.
How do you take anti log?
To take the antilogarithm of a number, you raise the base of the logarithm to the power of that number. For example, if you have a logarithm with base 10 and you want to find the antilog of ( x ), you would calculate ( 10^x ). Similarly, for a natural logarithm (base ( e )), you would compute ( e^x ). This process effectively reverses the logarithmic operation, yielding the original value before the logarithm was applied.
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 is a natural logarithm?
That is a logarithm to the base "e", where "e" is a number that is approximately 2.718.
What is a number for which a given logarithm stands?
A number for which a given logarithm stands is the result that the logarithm function yields when applied to a specific base and value. For example, in the equation log(base 2) 8 = 3, the number for which the logarithm stands is 8.
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.
Is a logarithm an irrational number?
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 is twice the base of the natural logarithm?
The "base of the natural logarithm" is the number known as "e". It is approximately 2.718.
How a number can be written in the form of logarithm?

What is antilogarithm?
The Logarithm of a number is the converse of its logarithmic value..
Is the base 2 logarithm of 32 a rational number or an irrational number?
Rational.
What is the logarithm L of a number x if 0 is greater than x?
Within the real numbers, the logarithm of negative numbers is not defined.
Is it possible for a logarithm to equal a negative number?
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
