Common sense. 108 = 100,000,000
10-8 = 1/100,000,000
To determine the value of 10 to the power of -8, we can take the reciprocal of 10 raised to the power of 8. Since 10 to the power of 8 is 100,000,000, the value of 10 to the power of -8 is 1 divided by 100,000,000, which equals 0.00000001.
To calculate six times ten to the negative power, multiply 6 by the value of ten raised to the negative power. For example, if the power is -3, it would be 6 times 10 to the negative third power, which equals 0.006.
The decimal point is moved to the left by the value of the power.
Order of magnitude
Eight: pH is defined as the negative of the logarithm to the base 10 of the actual value.
it is 1/100,000,000 or 1/10 to the negative 8th power.
Common sense. 108 = 100,000,000 10-8 = 1/100,000,000
It is: 10-8 is 1/108 = 0.00000001 or 1*10-8 in scientific notation

10 to the negative 12 power
10 x 10 x 10 = 1000
1x10^-6 = .000001 4.5x10^-6 = .0000045
