when you add 2 logs do you multiply the insides?
if they have the same base?
or do you just add the inside?
multiply
i thought it was the inverse of what you just said
and divide when subtracting?
And divide if subtract
por ejemplo
2log(x-3)+log(x+2)-6log(x)
-4log((x-3)(x+2)/(x))?
bring the multiplies into the log
2log(x-3)= long (x-3)^2
long
long!
long lol
but like
oh boi
yes
a*log(b) = log(b^a)
yes i know that
as a log rule
but that seems hard XD
its not
what are you even solving for?
no clue how much it wants you to simplify
im simplifying
there is nothing to reduce in these questions though
I would assume log (
i mean thats what i have
its just changing the form
No clue if it wants you to multiplu through
i dont feel like it would be necessary to go further
cause it wont simplify any more
I assume he is just being made to practice log rules leg
then he should be told to condense the logs
Probably, but I imagine this is what is needed
the coolest log formula is
log_a(x) = log_b(x)/log_b(a)
is that what I wrote here
converthing bases
yes
that is a cool formula
its actually quite useful for computer science runtime analysis
I can imagine
I like how I now have two different people to ask me questions Kappa
Been helping Umbreon with his physics and math
why do probability professors make such a big deal over Bayes theorem?
No idea, considering I do not know what that is
its such an easy to grasp concept
its just an equation for determining probability of future events based on prior knowledge
Have not done anything probability in uni yet
third year hype
alright
got another
ima just take a pic of this one
How to do m
what is the second exponent?
and exponent to an exponent do you add or mulitply?
second is -1/2
pic is pretty clear
i think
i have no idea what to do here
let r = (1-2x)^(-1/2)
r(1+xr^2)
go on
r(1+x/(1-2x))
x
1 + ------
1-2x
----------
√(1-2x)then multiply top and bottem by sqrt 1-2x?
then do more stuff?
that just returns it back to the original problem
so leave it like that?
i don't know, your class is too vague
it literally just said "simplify" and then listed a shit ton of expressions
@Phijkchu_Pikachu
Which question
