a^(n)-b^(n)
=(a-b)^(n)+nk(a-b)
here when "a" is an odd natural number , "b" is any natural number other then "a" and "n" is any prime number or its factors are the same prime (the numbers whose multiples are 5 like 25 ,125 etc are excluded but the case of 5 is included.) then "k"will always be a natural number.
give an example to prove it wrong.

I am thinking of buying a heater that looks like a wood stove, but it is electric. My other alternative to supplement heat in my house is a pellet stove. I can't read darn conversion tables on watts to kilowatt hours to save my life. If I run this 1300 watt heater 24 hours per day for 30 days a month, I need to know how many kilowatt hours KWH it will use to figure out how much it will cost me...please, help me you math wizards!

I was recently reading Steven Hawking's "The Universe in a Nutshell," and he said that time comes to an end in a Black Hole.

He also says that the Black Holes will eventually diffuse, and the energy released will contain information about what fell into the Black Hole.

This creates a paradox to me, something is apparently changing inside of the Black Hole if it retains information, yet he says there is no time. How could a change occur with no time?

Is the vastness of space the single greatest reason that we have not yet made contact with an E.T. I personally believe that any race smart enough to cross the gulf of space wouldnt contact us because we would be to primitive for them to care about us. They might study us.......

How do you figure out what a digital gate senses as HIGH and LOW? I
thought it was labeld VIH, VIL, VOH, and VOL. But ive been told that by
setting VIH you can set what VOH is. Totally confused by this. I
thought there was a specified range, and that was what you used.
According to other people you could, "set", and have a VIH at 1 Volt.
How do these setting really work?

Why do images of atoms look like little balls? If (as I suspect) we're seeing the outermost electron shell of the atom, why are they all spherical? And since the 'shell' isn't really a shell, what are we seeing?

A circle C1 with centre O1 exists. Inside it exists another circle C2 with centre O2 just touching C1 at A.Another circle C3 ,passing through O2 also touches C1 at B meeting C2 at P and Q a line through PQ touches C1 at X and Y.X and Y are joined to B meeting C3 at F and G respectively.Prove that FG is tangent to C2

Isn't it an absurd forced fed conclusion on an ill conceived newly minted definition that sets aside a fact no less than a planet as if it were a speck? Or is it a genial definition that defying all odds and opposition straightens out the Milky Way map?
