What is the inverse of exponentiation?
What is the inverse of exponentiation?
In mathematics, the logarithm is the inverse operation to exponentiation, just as division is the inverse of multiplication and vice versa. That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number.
How does logarithm relate to exponentiation?
In its simplest form, a logarithm is an exponent. Taking the logarithm of a number, one finds the exponent to which a certain value, known as a base, is raised to produce that number once more.
What is the inverse of logarithm?
The inverse of a logarithmic function is an exponential function. When you graph both the logarithmic function and its inverse, and you also graph the line y = x, you will note that the graphs of the logarithmic function and the exponential function are mirror images of one another with respect to the line y = x.
What is the symbol for logarithm?
The logarithm is denoted “logb x” (pronounced as “the logarithm of x to base b”, “the base-b logarithm of x”, or most commonly “the log, base b, of x”).
What is the logarithm with a base of ten?
the common logarithm
In mathematics, the common logarithm is the logarithm with base 10. It is also known as the decadic logarithm and as the decimal logarithm, named after its base, or Briggsian logarithm, after Henry Briggs, an English mathematician who pioneered its use, as well as standard logarithm.
What are exponentials and logarithms?
Sections: Introduction to logs, Simplifying log expressions, Common and natural logs. Logarithms are the “opposite” of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs “undo” exponentials. Technically speaking, logs are the inverses of exponentials.
How do you work out logarithms?
The relationship between ln x and log x is: ln x = 2.303 log x Why 2.303? Let’s use x = 10 and find out for ourselves….CALCULATIONS INVOLVING LOGARITHMS.
| Common Logarithm | Natural Logarithm |
|---|---|
| log x/y = log x – log y | ln x/y = ln x – ln y |
| log xy = y log x | ln xy = y ln x |
| log = log x1/y = (1/y )log x | ln = ln x1/y =(1/y)ln x |

What is the logarithmic form 10³ 1000?
In the example 103 = 1000, 3 is the index or the power to which the number 10 is raised to give 1000. When you take the logarithm, to base 10, of 1000 the answer is 3. So, 103 = 1000 and log10 (1000) = 3 express the same fact but the latter is in the language of logarithms.
