1,4,5 are what i need help with.
OpenStudy (anonymous):
ok lets do number 1 :)
OpenStudy (anonymous):
\[clog_{b}a=\log_{b}a ^{c}\]
using this formula, can u tell me wat u think is the answer to number 1?

yes :)
OpenStudy (anonymous):
can u do number 4 now?
OpenStudy (anonymous):
G
OpenStudy (anonymous):
no, now given this
\[4\log_{3}x+7\log_{3}y = \log_{3}x ^{4} + \log_{3}y^{7}\]
try again :)

the answer is F
OpenStudy (anonymous):
beacause \[\log_{b}a+\log_{b}c=\log_{b}ac\]
understand? also when ur back plz stay so we can finish this lol
OpenStudy (anonymous):
ohhh i get it @HawkCrimson
OpenStudy (anonymous):
cool now number 5 :D
OpenStudy (anonymous):

\[-\log10^{-7}-(-\log10^{-14})\]
Try to do number 5 part a now ;)
OpenStudy (anonymous):
i keep getting nan
OpenStudy (anonymous):
i know it says don't use a calculator,but i can't do it without it
OpenStudy (anonymous):
lol that is because they want u to simplify it
OpenStudy (anonymous):
ill show u how now

OpenStudy (anonymous):
\[-\log10^{-7}+\log10^{-14}\]
\[\log10^{-14}-\log10^{-7}\]
\[\log(10^{-14}/10^{-7}) = \log10^{-7}\]
OpenStudy (anonymous):
\[\log10^{-7}\] \[-7\log_{10}10\] Since, \[\log_{a}a=1\] Then, \[\log_{10}10 = 1\]
Therefore, -7(1) = -7
-7 is ur answer :)
OpenStudy (anonymous):
understand?
OpenStudy (anonymous):
ohhhhhh i get it
OpenStudy (anonymous):
cool now part b, u give it a try :)
