Hi,
can someone explain why: $\displaystyle 2e^{-ln(2)}=1$
I understand what the answer would be if the negative wasn't there.
Thanks,
Matt
Two basic properties of the exponential function and its inverse...
$\displaystyle \forall a > 0$ , $\displaystyle e^{\ln a} = a$ (1)
$\displaystyle \forall b$, $\displaystyle e^{-b} = \frac{1}{e^{b}}$ (2)
Kind regards
$\displaystyle \chi$ $\displaystyle \sigma$
