2 to the power of 20 divided by 4 to the power of 10 is equal to one.
10 to the negative 12th power is equal to 1 divided by 10 raised to the 12th power. This can be simplified to 1 divided by 1 followed by 12 zeros, or 0.000000000001. In scientific notation, this would be written as 1 x 10^-12.
If it is to a (-) power then that is the same as saying it is 1 divided by 2 to the power of 1. 2 to the power of 1 is 2, and so 1 divided by 2 is 1/2 or 0.5.

first you forget the 2 is there. then you go : 1/10 x 1/10 x 1/10 x 1/10 x 1/10 x 1/10 = b now make b a 2. 2 x 10 -6 is 0.000002.
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
