Mate, your mouse pointer got cold and it's shivering, may be your computer hasn't wormed up yet.

Just kidding, thanks for your help anyways.

@ymsphaa If it was then it would be going mad now. -5 here at present.

hey buddy... i thought you only use that specific formula when dealing with negative powers or numbers >1 ... what about the formula with the combinations and things where you use pascals triangle...? :) good video btw

[ExamSolutions]

@kiddyflo This is a universal formula and can be used all the time. However, it may be easier to use the combinations method or Pascals triangle when the power n is positive.

@ExamSolutions muchas gracias... :)

hoooray!

You've probably saved me a lot of marks as I tend to drop quite a few when using Pascal's triangle. This is much easier and cleaner so thanks a lot.

[ExamSolutions]

cool

Very well done. Similarly to Hellfire257, I agree that you explained the concept better than my math teacher did...

[Hellfire257]

Thank you very much - you explained it a lot clearer than my teacher did!

[ExamSolutions]
