C4 Guesses!

motherheaven:
c3 paper was pretty easy .so i have some feeling that c4 paper will be very tough

Hwa1:
thats wat i was thinkin 2, plz dnt remind me lol
id rather it was the other way round tbh...because a 'hard' c3 is still easy.

guys if u got
ln A = B + ln C
and u wna get rid of the ln's by doin the thing with e
do u do it to the left and right sides as a whole or seperate?
like will it be:
 A = e^B + C
OR
 A = C x e^B

motherheaven:
it will be
ln A = B + lnC
ln A - ln C =B
ln ( A / C ) = B
    A/C = e^B

Hwa1:
thanks
meh, there was a Q in c3 where we had to factorise something with e's
but i almost fell asleep and startin takin ln's, but that was wrong too because i was doin it to the stuff singularly rather than the sides as wholes...that sucks, 90% in c3 or sumfin im guessin.. :(

theman:
@motherheaven

Yea thts true C3 was pretty easy so they may kill us in C4.

But My S1 was great and C3 too, so hopefully they ll make up!

@Hwa1

B=lnc-lna

B= ln (c/a)

e^B=c/a
