DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.

is OR

= 1, where a ≠ 0

Step-by-step explanation:

To simplify the exponents, you must put it in positive value

Example:

The simplest form of is to change the exponent from negative value to positive value.

That means if you want to simplify , reciprocal a and change the sign of the power from -n to n

The simplest form of is OR

For any number, a (a ≠ 0), 1 × a = a, 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)

Example:

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 a ≠ 0

Very important note:

is undefined value
