Ok
Another question
I guess by this time you might've guessed I"m absolutely stupid and a dunce. But I have to know this.
ok so how does lnx=1/2 becomes e^lnx=e^1/2 ?
I don't know this.
what do you do to make it like this?
I'm sorry but as you see I don't know much about ln and log and e and stuff.
Ok thanks again.
astarmathsandphysics:
To eliminate a log you raise the base to the power of both sides. Here the base is e=2.718.........
nox_fjmoony:
Ah
Finally
I get it. Thanks so much, wouldn't have known this without you tellin me.
Thanks again.
;D
nox_fjmoony:
