Question

question attached inside!! :)

Answer 1

part 1 of question :)

Answer 2

part 2 (last part!) of the question :)
they are connected, but just one problem :)

Answer 3

A. -1

B. 27

C. 29

D. There isn't enough information to answer the question.

idk :/

Answer 4

all logs in this particular problem are base b

Answer 5

kk so that means? haha :P

Answer 6

log( (A^5C^2)/(D^6) ) = log(A^5C^2) - log(D^6)

log( (A^5C^2)/(D^6) ) = log(A^5) + log(C^2) - log(D^6)

What's next?

Answer 7

no i said that as a disclaimer to what I was about to write

Answer 8

oh okay haha :P so do i simplify that more? or is that the most simplified it can get?

Answer 9

or do i do substitution or sometihng?

Answer 10

you can pull the exponents down

Answer 11

using one of the rules given on that purplemath site

Answer 12

oh no!! i lost the link :(

Answer 13

can u pls resend it to me? :)

Answer 14

Answer 15

okay so which one do i use?? I'm confused :(

Answer 16

you use the rule that log(x^y) = y*log(x)

Answer 17

so I'm trying to see what to put in here, but I'm stuck... idk :(

Answer 18

log( (A^5C^2)/(D^6) ) = log(A^5C^2) - log(D^6)

log( (A^5C^2)/(D^6) ) = log(A^5) + log(C^2) - log(D^6)

log( (A^5C^2)/(D^6) ) = 5*log(A) + 2*log(C) - 6*log(D)

Then do the proper substitutions

Answer 19

ohhh i see what u did now! but how do i do proper substitutions??

Answer 20

log(A) = 5, so replace log(A) with 5

do the same with the other logs

Answer 21

so i get log(5)+log(2)-log(6)
??

Answer 22

close

Answer 23

you mixed up C and D though and you're missing your coefficients

Answer 24

okay then, idk then :( iheartfood=a confused person atm :/

Answer 25

look at the givens again

Answer 26

the givens?

Answer 27

what are the givens?? from the original question?

Answer 28

yeah, log(A) = ..., log(C) = ..., etc

Answer 29

okay so i get this?
log(5)+log(7)-log(2)
??

Answer 30

ok, now add on the coefficients

Answer 31

what coefficients?? like the results when i enter it in the calc??

Answer 32

oh wait, idk why i said that was right, I'm misreading lol

Answer 33

log( (A^5C^2)/(D^6) ) = log(A^5C^2) - log(D^6)

log( (A^5C^2)/(D^6) ) = log(A^5) + log(C^2) - log(D^6)

log( (A^5C^2)/(D^6) ) = 5*log(A) + 2*log(C) - 6*log(D)

log( (A^5C^2)/(D^6) ) = 5*5 + 2*7 - 6*2

log( (A^5C^2)/(D^6) ) = ???

Answer 34

log(A) = 5

NOT log(5)

Answer 35

wiat so what do i have now then?? I'm confused now lol

Answer 36

no sry, but i put up the right way to do it

Answer 37

so i have this so far???just making sure... idk if thats how I'm supposed to draw it?
