Question

Write 2log35 + log32 as a single logarithm

Answer 1

\[2\log _{3}5 + \log _{3}2\]

Answer 2

will give medal

Answer 3

logarithmic properties, coocoobird

Answer 4

alright could you give me the property i need to use for this equation

Answer 5

Answer 6

i don't know what to do with the 2 in front of the first log

Answer 7

\[\Large b\cdot\log(a) \quad=\quad \log(a^b)\]

Answer 8

it looks like this property logb(xy) = logbx + logby.
but what happens to the 2

Answer 9

b=2

Answer 10

well, you have to read the contents of the link I gave you

Answer 11

then you would know what to do

Answer 12

is 3 a?

Answer 13

no. 3 is the base.

The rule i posted above deals with the 2 and 5.

Answer 14

\[alog_{n} r = \log_{n} r^{a} \] and \[\log_{n} a + \log_{n} b = \log_{n} (ab) \]. @katherinesmith these are the two properties you need for this particular question.

Answer 15

there's nothing that they're telling you now that is not in the link…

Answer 16

so i'm down to 3 * log(2) = log8

Answer 17

now what

Answer 18

read

Answer 19

3log(2)=log(8)?? :O

Answer 20

lol

Answer 21

@nincompoop if i wanted a link to a website about logarithms i could've googled one. i'm on this website because i need serious help with math because logarithms are not easy to understand when you have to learn about them online. so stop telling me to read.

Answer 22

2^3 = 8 dohhhhhhhhhhhhhhh

Answer 23

Katherine, i've been posting the same formulas several times on your posts.
You just don't seem to be getting it.

It would really be a good idea to read up on logs maybe :c

Answer 24

they're easy to understand, but you need to read about them first. this website is not for spoon-feeding solutions

Answer 25

i don't want spoon feeding, i understand the process of having formulas you have to go through but i don't know which ones to use. i don't know.

Answer 26

@nincompoop the link is too general for this situation. Give her something particularly suited for this situation.

Answer 27

it's the same in all cases

Answer 28

@katherinesmith did you see the exact formulas you need for this problem?

Answer 29

Answer 30

Example of the rule I posted above:\[\Large 3\cdot \log_4(x) \quad=\quad \log_4(x^3)\]
Will that help you apply it to your own problem maybe kath? :o
See which numbers are going where?

Answer 31

yes thank you for helping me.

Answer 32

i'm gonna work on it and close the question. i don't need tension over a math problem. i have plenty other questions to ask.
