Exponentiation Basics: Convert -ve Indices to +ve

[Raabi]

Hello everyone!

I am a new member of this forum and this is my first post. At the moment, I am looking for the solution for the following:

(x^-m - a^-m)/(x - a)​

I intend to change the -ve indices into +ve.

Thanks, in anticipation, for any help.

Regards.

Hello!

Ok, so what do negative indices mean? How would you express x^{-m} with a positive index?

 

[Raabi]

Thanks for the response, Mentallic. Yes, I meant that; but I have solved the problem. Have a nice time.

Please do not post a thread and then refuse to answer any questions about it! Mentallic was trying to find out if you knew that x^{-m}= \frac{1}{x^m}

Halls, the guy did nothing wrong. If he claims to have figured out the problem then I'm sure he knows the answer to my question.

Good luck with your studies Raabi!
