Question 1978: If p=3^(20-q) using logarithms express q in terms of p
Answer by longjonsilver(2297)   (Show Source): You can put this solution on YOUR website!
take logs to base 3,
logp = 20-q
so q = 20 - logp
where log is log_base3: if p=9, then logp would be 2, then q=18.
in the original...3^(20-18) is 3^2 --> 9
so 2 equations are equivalent
