How to cancel out log base 10?
How to cancel out log base 10? Explanation: In order to eliminate the log based ten, we will need to raise both sides as the exponents using the base of ten. The ten and log based ten will cancel, leaving just the power on the left side. Change the negative exponent into a fraction on the right side.
What cancels out natural log?
logₑ (e) = k. We want to find the value of k that makes this equation true: eᵏ = e. Well, as you know, anything to the 1 power is equal to that same thing, so: e¹ = e. k = 1. This is why e cancels out the natural log: logₑ (e) = 1. ln (e) = 1.

Do log and ln cancel?
The logarithms and exponentials cancel each other out (equation (4)), giving our product rule for logarithms, ln(xy)=ln(x)+ln(y).

Can we cancel log with log?
If you have the same operation on both sides of an equation, they cancel each other out! Keep in mind that this only works when the logarithms on both sides of the equation have the same base. If you had a logarithm with base 3 on one side and a logarithm with base 7 on the other side, they won't cancel out.

What is opposite of ln?
The natural logarithm function ln(x) is the inverse function of the exponential function ex. When the natural logarithm function is: f (x) = ln(x), x>0. Then the inverse function of the natural logarithm function is the exponential function: f -1(x) = ex.

What is inverse of log?
Some functions in math have a known inverse function. The log function is one of these functions. We know that the inverse of a log function is an exponential. So, we know that the inverse of f(x) = log subb(x) is f^-1(y) = b^y.

Symptoms
If you frequently view many EVT or EVTX files in Event Viewer (eventvwr.msc), you may notice a large number of files have accumulated under Saved Logs. These entries are persistent even if the original EVT and EVTX files have been deleted.
Cause
Event viewer stores saved log locations in .XML format. The .XML files can be found in the following directory. %programdata%\Microsoft\Event Viewer\ExternalLogs
Resolution
The following command can be run from a command prompt to purge the Saved Logs. del /s /q %programdata%\microsoft\eventv~1\extern~1 You can also browse to the following location and delete the logs manually: C:\ProgramData\Microsoft\Event Viewer\ExternalLogs
More information
Event Viewer reads the saved log locations when it starts and saves them when it is closed. The following actions should be taken to guarantee Saved Logs are deleted properly.
Where are Windows log files?
Usually, you can find the log files by going to the path (depending on Windows versions) - C:WindowsSystem32winevt or C:WindowsSystem32config. However, these log files may be large and take up much disk space of the hard drive. To free up disk space, you may choose to delete them.

Remove Files Based on Last Modified Date
If you want to clear your existing log files based solely on the last modified date of the file, all you have to do is use the FORFILES command. For example:
Remove Files Based on a Date Pattern in the File Name
Many applications and services produce log files based on a date pattern as to have one log file per day (i.e. Log100113.txt, Backup-2010-01-13.zip, etc.). For these types of files, it is preferable to delete based on the date of the file incorporated into the file name rather than the last modified date.
Automating the Process
The FORFILES command is native to Windows, however the DeleteByDatePattern script should be placed in a folder defined in your Path variable (such as your Windows folder) so it can be called as though it were a native command.
