hey thanks Astar.
But you see its where the e part that I don't understand. I'm just starting add maths for the october november session and well I really don't understand how to get the e thingy.
And thanks a lot again.
^_^

astarmathsandphysics:
I edited my post to make it clearer.

To solve the equation y=lognx raise the base to the power of both side so ny=x

astarmathsandphysics:
ln x is special notation for lognx=lnx

nox_fjmoony:
thanks
but
I have a problem in another part
The part where it becomes x=e^1/2 all of a sudden. I'm quite outta practice and so don't quite understand it. Didn't understand that part in the mark scheme either.

Also whats the relationship between ln and e please?
Thankyou very very much Astar. ^_^

Really grateful.
:D

astarmathsandphysics:
so lnx=1/2 so so
