No P/N and M/N

ok $\ln (p/n) = 6, \ln (m/n) = 8$

What's the relationship ? Is it M=100P

4. dumbcow

using the log property ..... log a - log b = log(a/b) $\ln p - \ln n = 6 \rightarrow \ln n = \ln p - 6$ $\ln m - \ln n = 8$ using substitution $\ln m - (\ln p - 6) = 8$ $\ln m - \ln p = 2$ $\ln (m/p) = 2$ .... assuming log base 10, then yes m/p = 100 or m = 100p
