How turn a negative exponent into a decimal?

To convert a negative exponent into a decimal, first rewrite the expression by taking the reciprocal of the base raised to the positive exponent. For example, ( a^{-n} ) can be rewritten as ( \frac{1}{a^n} ). Then, calculate the value of ( a^n ) and take its reciprocal to find the decimal representation. This process effectively transforms the negative exponent into a positive one in the denominator.
