Why is a number raised to the zero power ALWAYS one and never any other number?

Do you know how to simplify, let's say for example,    x⁵/x²  ?

When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator.  So  x⁵/x² = x³ .

Now look at  x⁷/x⁷ .  From that same handy tip, x⁷/x⁷ = x⁰ .

BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '.  So  x⁰ = 1 , no matter what 'x' happens to be.

Does that do anything for you ?
