For the equality becomes
For a>1, b>1, show that (logab)(logba) = 1.
The variable after the log is the base.
How do I go about showing this?
I already know these:
Logbx = Logax / Logab
(again, the variable after the log is the base, i don't know how to write it properly on this forum)
and, Logtb = 1 / Logbt
(variable after log is base)
How do I approach / solve this problem?
