I'm not sure if I'm correct...
if I have expression log(a)*log(b)=log(c)
Can I change it to a*b=c ? Or anything if possible.
No. Because....
If you have a*b=c and you take logs of both sides you get
log(a*b)= log c . Now log(a*b) = log a + log b, and not log (a)*log(b)
No, unfortunately, there's not much you can do......it is tempting to want to get rid of the logs and solve a * b = c.......however.....we can quicly see that this will not work.......consider this.... [I'm using 10 as the base]
log(100) * log(1000) = log (1,000,000) which is true
But
100 * 1000 ≠ 1,000,000
So.....in general, for
log(a)*log(b) = log(c)
a * b ≠ c
