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
Eight: pH is defined as the negative of the logarithm to the base 10 of the actual value.
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.
The result will be a negative value.
The value of 3 to the negative power of 2 is 1/9.
negative
68
6
its 16, because the value of the power is even so the negative has no effect.
The value of 5 to the negative 4th power (5-4) is 0.0016
5.0119x10 to the power of -6 or 0.0000050119
Negative, because 5 is an odd number
