Revise Log For Free

The natural log, or ln, is the inverse of e. The letter 'e' represents a mathematical constant also known as the natural exponent. Like ?, e is a mathematical constant and has a set value. The value of e is equal to approximately 2.71828.

Taking the logarithm of the equation (with any base) yields: where m = k is the slope of the line (gradient) and b = log a is the intercept on the (log y)-axis, meaning where log x = 0, so, reversing the logs, a is the y value corresponding to x = 1.

To rid an equation of logarithms, raise both sides to the same exponent as the base of the logarithms. In equations with mixed terms, collect all the logarithms on one side and simplify first.

Let's look at this example here we've got log base 5 of 125th.

Answer and Explanation: Using this formula, we can convert log base 2 to log base 10, where log base 10 is called the common logarithm, and we denote log10 (x) as log(x). The change of base formula gives the following: l o g 2 ( x ) = l o g 10 ( x ) l o g 10 ( 2 ) = l o g ( x ) l o g ( 2 )

The logarithmic function is given by y = log b ? x , where b is the base, and b 0 , b ? 1 , x 0 if and only if x = b y . The standard base of the logarithmic function is 10. The inverse of log function is an exponential function.

Then we swap the x and the y's. Right and now we solve for y.
