Question

If log M/N=5 and log P/N=7, what can you say about the relationship between M and P?

a. P = 2M

b. P = 10M

c. P = 100M

d. M = 2P

Answer 1

\[\large \log \frac{ P }{ N } - \log \frac{ M }{ N } = 7 -5\]
simplify this first

Answer 2

the right hand side, what does it then become?

Answer 3

2?

Answer 4

yes. now.
split the logs on the left hand side using:
\[\log \frac{ a }{ b } = \log a - \log b\]

Answer 5

what do you get?

Answer 6

i dont know
