1).a^(n)-b^(n)can be expressed as
difference of at least one set of two squares
like 7 ^ (3) - 4 ^ (3) = 48 ^ (2) - 45 ^ (2)
2).any number say c having any power n can be
expressed as difference of at least one set of
two squares like
7 ^ (3) = 172 ^ (2) - 171 ^ (2)
from this prove that
a ^ (n) - b ^ (n) = c ^ (n)
is not possible.
hint :- (any number) ^ (n) cannot be 0 for any value of n.

Can anyone enlighten me as to how the process of autumnal (fall) colours in leaves originated? One would think that (in evolutionary terms) there couldn't be anything to gain from a stunning display of autumn colours, and that it would be more energy efficient for the trees to simply let their leaves simply shrivel up and drop off as winter approaches. So what's in it for the trees?

Please note I'm asking who invented it not who patented it. I heard a good story about the conception of the idea and am trying to investigate further. I'm talking about the wood drill bit that is commonly used. I know the name Auger derives from the person who patented it but who actually came up with the idea?

if a ^ (n) - b ^ (n) =c ^ (2) - d ^ (2) like
7 ^ (3) - 4 ^ (3) = 48 ^ (2) - 45 ^ (2) &
a ^ (n) or b ^ (n) can be expressed
as difference of two at least one set of two squares also like
7 ^ (3) =172 ^ (2) - 171 ^( 2) or any number
say x having any power n can also be expressed
as difference of at least one set of two squares i.e
x ^ (n) = h ^ (2) - j ^ (2)
prove that a ^ (n) - b ^ (n) = x ^ (n)
is not possible.a,b,x are natural or rational numbers and n is
a natural power.
hint :- (any number) ^ (0) is undefined.

Here's a silly word riddle!

What you have to do is to fill up all three blanks with with the same word.
The meaning of the word changes in each of the blank
For example : "forgot" can also be treated as "for" & "got".
So if you use "forgot" in one blank you can use "for got" in another!
