Explain in great detail IN WORDS, not with just an example how to simplify an expression that contains positive, negative, and zero exponents NEED HELP ASAP IT MUST BE RIGHT AND ATLEAST 40 WORDS

Negative exponents and zero exponents often show up when applying formulas or simplifying expressions.

In this section, we will define the Negative Exponent Rule and the Zero Exponent Rule and look at a couple of examples.

Negative Exponent Rule: b^{-2} = \frac{1}{b^n}

In other words, when there is a negative exponent, we need to create a fraction and put the exponential expression in the denominator and make the exponent positive. For example,

3^{-2} = \frac{1}{3^2} = \frac{1}{9}

But working with negative exponents is just rule of exponents that we need to be able to use when working with exponential expressions.
