alright
more ab calc shit
(x^(3/2)) * (x+x^(5/2)-x^2)
so x to the 2/3 times (x plus x to the 5/2 minus x squared)
if that makes more sense
what are you trying to do?
factor?
no because thats a different exponent
simplify
is it 3/2 or 2/3
yeah is it 3/2 or 2/3
not 2/3
by simplify, does it just want you to multiply through?
I am not sure what this question actually wants
x^5/2 + x^4 - x^3
thats simplified i guess
can you simplify it further though?
also do you mean -x^7/5?
what?
oh yeah i did math wrong
ok good
wait leg what do you major?
7/2
not 7/5
engineering?
7/2 yeah my b
ece
electrical and computer engineering
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
