PLEASEEE! Use properties of logarithms to solve the equation log(base3) y – log(base3) 7 = log(base3) 2

OpenStudy (anonymous):

your first part will be division... log(base3)(y/7)

OpenStudy (anonymous):

What are we supposed to do after that?

OpenStudy (anonymous):

trying to remember lol

OpenStudy (anonymous):

hah!

OpenStudy (anonymous):

i think you can divide both sides by log base 3 then that will give you a normal equation

OpenStudy (anonymous):

so y/7 = 2, y=14

OpenStudy (anonymous):

how does y/7 = 2?

OpenStudy (anonymous):

since we got rid of the logs by dividing both sides by log base 3

OpenStudy (anonymous):

ohhh okay! thanks!

OpenStudy (anonymous):

khan academy has really good videos on this subject, it helped me a lot when i did these types of problems

OpenStudy (anonymous):

ill check them out thanks. appreciate it.
