for expanding negative powers of a number you take 1 divided by the number to the positive power and expand. For example 2 to the -1 power is 1 divided by 2 to the + 1 power = 1/2 2 to the -3 power is 1 divided by 2 tot he + 3 power = 1/8 this is called inverse
6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
