Question

Rewrite as a logarithmic equation.
e^9 = y

debbieg · Answer

In general:

$$\Large b^x=y$$ means that $$\Large \log_{b} y=x$$

debbieg · Answer

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.

debbieg · Answer

So just apply that, with base of e.

anonymous · Answer

is it correct?

anonymous · Answer

And long with a base of e is ln right?

debbieg · Answer

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

debbieg · Answer

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

anonymous · Answer

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