Example: Let's say b-8.2, where b is an integer.

First step, turn the negative exponent to a positive one, and then use the laws of exponents.

b-8.2

= 1/b8.2

= 1/b8+1/5

= 1/[b8b1/5]

= 1/b8 * 1/b1/5

= 1/b8 * {1(b4/5)/[(b1/5)(b4/5)]}

= 1/b8 * b4/5/b(1/5)+(4/5)

= 1/b8 * b4/5/b5/5

= 1/b8 * b4/5/b

= b4/5/b8+1

= b4/5/b9
