Answer 3

That is, \(\Large \log_{b} y=x\) means that x is the POWER to which you raise the base b to get the result, y.

Answer 4

So just apply that, with base of e.

Answer 5

is it correct?

Answer 6

And long with a base of e is ln right?

Answer 7

And keep in mind, \(\log_{e} a=\ln a\)

Answer 8

Right - it's a "special notation" for the log function with base of e.

Answer 9

yes, it's the "natural logarithm" (logaritm naturali) for the base e
