also, when you said :

a^x = e^lna. x


is that x.e^(ln a) or e^(x ln a) ?????????????
e^(x lna)

demonstration is simple

you know that

(a^b)^c = a^bc ...well you should

and so backwards a^bc = (a^b)^c

so e^(x lna) = (e^lna)^x = a^x

I thought she meant ln(ax)... ambiguous. Use reverse polish.

I'll leave a hand written proof on your desk.

so lex i have

Y = ae^(t ln b)

so if i ln that, i get ln Y = ln a + t ln b? is that eright?

no, it applies to the ketters in any form, spoken, handwritten, typed, sprayed in 6 foot letters on my ceiling...

ok, net question, how do i sketch a graph of Y = ae^(t ln b) ? of Y against t?

If you want a straight line, you don't plot y against t. You plot LnY against t.
