What is 27.9 as a decimal?
27.9 IS a decimal number. You can tell it is a decimal number because it has a decimal point (.).
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.
How can you tell if a decimal is an irrational number?
When a decimal can't be expressed as a fraction then it is an irrational number.
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 does a decimal number tell you?
It tells you the value (and sign) of the number.
What is the definition of mantissa?
The decimal part of a logarithm, as distinguished from the integral part, or characteristic.
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 can you make logarithm table?
To create a logarithm table, start by selecting a base for the logarithm, commonly base 10 (common logarithm) or base e (natural logarithm). Calculate the logarithm values for a range of numbers, typically from 1 to 100, using the logarithm formula or a calculator. Record these values in a table format, listing the numbers in one column and their corresponding logarithm values in the adjacent column. Ensure to include necessary decimal places for accuracy and consider adding interpolation for non-integer values.
