Differentiation of logx is equal to 1/x ....here what is the base of log
Its natural log..... so its nothing other than e
The base of log is always e. And logx to the base e is mostly written as ln x.
Mostly it's e.....but if it's 10 den convert it to e den solve
Mostly in physics it's e
If base is not. Given then its considered e
Base could be anything except 0&1
