cara.mel:
is there like a list which puts Exponential Rule next to corresponding Log rule?

LIke I remember e^a*e^b = e^(a+b) is related to log a + log b = log ab
what are the other ones paired up with
I don't think I know all the exponential rule but I know that one because if it was like e^2*e^3 = (e*e)*(e*e*e) = e^5

We know that

If we do the same thing to both sides of an equation, it stays the same.

both sides



Using log laws, which Mao has already proved.

cara.mel:
thank you everyone :):)
so is Log like ^ and arcsin and stuff?

Eg
sin theta = 0.5
arcsin (sin theta) = arcsin (0.5)
theta = arcsin (0.5)

Mao:
yes

log is defined as the inverse of the logarithm function
