If log(m/n) = 4 and log(p/n) = 5 what is the relationship between m and p? p=100m p=10m p=0.1m m=10p

Log(A/B) = logA - logB    By law of logarithm

log(m/n) = 4

logm - logn = 4    (a)     

log(p/n) =5

logp - logn = 5    (b)

Equation  (a) minus  (b)

logm - logp - logn - (-logn) = 5 -4

logm - logp - logn + logn = 1

logm - logp   = 1

log(m/p) = 1

log₁₀(m/p) = 1.

All the while the logarithm has been to base 10. Once a base is not written in logarithm, it is taken to be base 10.

  log₁₀(m/p) = 1

(m/p) = 10¹           conversion from logarithm to indices

m/p = 10

m = 10p
