Question

Logarithm question.

Answer 1

\[Log _{(Log_5x)}\]is there any way to simplify this?

Answer 2

Sorry but no :/

(just according to my knowledge)

Answer 3

@hartnn sorry I have to sleep now see you next week :D

Answer 4

I have another question about economics, can you help me with it?

Answer 5

After this q of course.

Answer 6

idku
the log has base of (log_5 x) ??
than what are you taking log of ?
or is it
\(\large \log_{\log5}x\)
i'd say the question is unclear...

Answer 7

I wrote it incompletely, sorry.
\[Log _{(Log_5x)}x\]

Answer 8

ok, so we need change of base rule
\(\large \log_ab = \dfrac{\log b}{\log a}\)
so how will u use it in your question?

Answer 9

I though that in my question where it's equal to zero, I can say,
\[Log _{Log_5x}x=0~~~~~~~~~->~~~~~~~~~~~Log _{Log_5x}x=Log_{Log_5x}1\]so x =1
Right?

Answer 10

no, x cannot be 1

if x= 1 the base of the log, which is log_5 x will become =0
and base of log cannot =0

Answer 11

true, so how would I solve it then?

Answer 12

you have to solve for x in that equation with = 0 ?
after solving you indeed get x=1
when we plug back in x=1, we find that x cannot =1
this means that x=1 is an ENTRANEOUS solution
and there is actually no solution for that equation

Answer 13

Thank you!

Answer 14
