is it the same as loge x^3 ? i don't think so though!
thx...in advance

(loge X)^3... how would you find the differentration for this..lol. forgot how to spell it!

thx...in advance
use the chain rule.

compare:
(log e)^3 =1^3 = 1
(log e ^3)=3 log e= 3
note: I used log to base e, that is ln.

Are you sure that logs are same?

Not sure what your concern is, but 'log e' by itself has no meaning, it has to be

I was refering to Damo17's statement that given logs are the same. however, he relized his mistake and edited his post (which is OK, we all make errors).Are you sure that logs are same?

Not sure what your concern is, but 'log e' by itself has no meaning, it has to be. It's like saying "calculate 3*", 3 times what?
and
Re log expressions, I just did not have time/skills to type mathematical notation of log x with base e and have used an example to show given logs are not the same.

Yeah, I was in a rush then.

i just wanted to clarify it so khalil is sure about the question.

that's ok Damo17,
i just wanted to clarify it so khalil is sure about the question.
Thanks for correcting me. I could have read this topic 100 times and still not have seen my mistake.
