Thanks, Bertie.....I see where I made my error (being in too much of a hurry!!)
Let's take it from here.....
log (10)(ab) = log ax by a property of logs, we have
log 10 + log ab = log ax and we have, using another log property
1 + (b) log a = (x) log (a)
(b) log (a) = [ (x) log (a) - 1] divide both sides by log (a)
b = [x - (1 / log (a)) ] ≠ x/10
Thanks again, Bertie, for your sharp eyes!!!....I forgot that the "b" exponent wasn't being applied to the "10" (I hope I got it right this time !!!)
If a^b equals (a^x)/10, will b equal x/10?
-----------------------------------------------------------------------------------------------------------------
Let's suppose that it's true multiply both sides by 10 we have
10ab = ax take the log of both sides
log 10ab = log ax by a property of logs, we have
b log 10a = x log a and using another log property, we have
b [log 10 + log a] = x log a and because log10 = 1 we have
b [1 + log a] = x log a solving for b, we have
b = [x log a] / [1 + log a] which is definitely ≠ x/10
