As long as the number isn't 0, we can derivie this from the Laws of Exponents.....

Note that    an / an =    an-n  = a0

But, any number divided by itself (except for 0)  is always = 1

Therefore...... an / an  = 1  →  a= 1

Note 00 is known as an "indeterminant" form......(we can't say what it is  !!!!)
