P=15000 e^0.05 (3) when i try to solve it with the calculator i try to put e^0.05 it appears 'sync error'...anhyway in order to transform it into an equation with In...should i do like this?
In 15000 x (o.o5 x 3 ) ?
When typing this term into your calculator you have to use brackets:
15000 * e^(0.05 * 3) will yield approximately 17427.5
e is a constant number (like pi). Maybe your calculator needs the input
15000 * exp(0.05 * 3)
If you want to use logarithms you may transform the given equation into:
$\displaystyle \ln(P)=\ln(15000) + 0.05 \cdot 3$
