And thenMoreNow it still needs to be raised to the third power so we'll raise it to the third power. And then close the parentheses. So now we have the natural log of e cubed.

As we know, any number raised to the power 0 is equal to 1. Thus, 10 raised to the power 0 makes the above expression true. This will be a condition for all the base value of log, where the base raised to the power 0 will give the answer as 1. Therefore, the value of log 1 is zero.

The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, when no confusion is possible, or when the base does not matter such as in big O notation.

Any exponential equation of the form ab=c can be written in logarithmic form using loga(c)=b. For example, the exponential equation 23=8 is written as log2(8)=3 in logarithmic form. The number after the equals sign in logarithmic form is the power that the base of the log is raised to to make the number inside the log.

The natural log function of 4 is denoted by ?loge 4?. It is also called the log function of 4 to the base e. The representation of the natural log of 4 is ln(4). The value of loge 4 is equal to 1.386.
