If they give us like this . We must put the e.g 6x differentiate then we must put xln6=any letter we ln it?
My purpose is to make the given function into either ln() or e^(), coz only these two functions can be differentiated.
But if they give it like that can i use that as a formula? The thing ure using e /ln and exactly following ur steps if thwy give 6x or 100x
It is not a formula, it is a method. You learned indices and logarithms in sec level, just make use of them.
But is there a diff way for me to do other than putting ........=k ?
I mean is there anyway to do it other than equalling the ln to k
k is just a temporary variable, a transition term only. I wanted to make it into an equation, so that you have LHS and RHS, so that I can rearrange. If only 10^x, which we call it an expression, I can introduce anything to balance it!
You can see eventually, I made k in terms of x too!

Some people who are good in indices and logarithms, they can straight away equate 10^x = e^(x ln 10) !!
The whole objective is to change the given expression into either ln or e^(), coz only these two can be differentiated, no other base or log...

Okay thank you! But this saturday i have parts that i dont understand from ur working. If ure free this sat can u help me explain those ? Please ?
I am quite loaded with tuition on Sat,maybe only free after 8pm++. Will try to log in here to help you. You may post your questions first.
But now the problem is, this apps is giving me Notifications problem, I can't read your comment, I need to trace back my History one by one to find your new comments, it is a long list!
Do you want to consider tuition with me at my home? It is cheaper than ever
