Answer:
is
OR 
= 1, where <em>a</em> ≠ 0
Step-by-step explanation:
To simplify the exponents, you must put it in positive value
<em>Example:</em>
The simplest form of
is to change the exponent from negative value to positive value.
- You can do that by reciprocal the number,

- You can write it
, because 1 to any power equal 1
That means if you want to simplify
, reciprocal <em>a</em> and change the sign of the power from -<em>n</em> to <em>n</em>
The simplest form of
is
OR 
For any number,<em> a</em> (<em>a</em> ≠ 0), 1 × <em>a</em> = <em>a</em>, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)
<u><em>Example:</em></u>
The value of
= 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)
That means
= 1, where <em>a</em> ≠ 0
