Question

if log(M/N)=4 and log(P/N)=5, what can you say about the relationship between M and P?

Answer 1

We can rewrite the two equations, using the rules of logs, as follows:
log P - log N = 5 .........(1)
log M - log N = 4 .........(2)

Subtracting equation (2) from equation (1) gives:
log P - log M = 1 ........(3)
Equation (3) can be written as:
$log\frac{P}{M}=1$
Therefore
$\frac{P}{M}=10$

Answer 2

P=10M- apex.

It is the correct answer
