Prove laws of logarithm?
Asked by simran2 | 5th Aug, 2010, 12:00: AM
logc (ab) = logc a + logc b
Proof: Let logc (ab) = d, logc a = e, logc b = f;
Hence, we can write, d = e + f ... (1)
cd = ab and ce = a, cf = b .. using logarithm definition,
Now ab = axb
cd = ce x cf
cd = ce+f
Which gives, d = e + f.
Similarly we can prove other laws.
