question!!!!!

OpenStudy (anonymous):

hiya!! do u get this?? :)

jimthompson5910 (jim_thompson5910):

one sec while i read it

OpenStudy (anonymous):

kk:)

jimthompson5910 (jim_thompson5910):

does it say anything about the base?

OpenStudy (anonymous):

no thats all... what i attached is the question and then the answer choices...

jimthompson5910 (jim_thompson5910):

hmm ok

OpenStudy (anonymous):

yeah... do u get it? :)

jimthompson5910 (jim_thompson5910):

yeah

OpenStudy (anonymous):

awesome!! how do u do this??

jimthompson5910 (jim_thompson5910):

log(M/N) - log(P/N) = 5 - 7 log(M) - log(N) - (log(P) - log(N)) = 5 - 7 log(M) - log(N) - log(P) + log(N) = 5 - 7 log(M) - log(P) = 5 - 7 log(M/P) = -2 log(M/P) = -2 M/P = 10^(-2) ... Assuming the log is base 10 M/P = 0.01 P/M = 10 P = 10M

jimthompson5910 (jim_thompson5910):

oh wait, hold on, typo...

OpenStudy (anonymous):

yeah I'm thinking its log base 10... :) and okay :)

jimthompson5910 (jim_thompson5910):

log(M/N) - log(P/N) = 5 - 7 log(M) - log(N) - (log(P) - log(N)) = 5 - 7 log(M) - log(N) - log(P) + log(N) = 5 - 7 log(M) - log(P) = 5 - 7 log(M/P) = -2 log(M/P) = -2 M/P = 10^(-2) ... Assuming the log is base 10 M/P = 0.01 P/M = 100 P = 100M

jimthompson5910 (jim_thompson5910):

fixed

OpenStudy (anonymous):

kk so this is my answer?? C. P = 100M 100% sure ? :)

jimthompson5910 (jim_thompson5910):

yes

kk thx!!
