Logarithmic functions are the inverses of exponential functions. The inverse of the exponential funtion y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. A logarithm is really nothing more than an exponent.
2x10^-10
1x10^-10
8x10^-11
7x10^-11
18.6/930= 0.02
2.2/13.75=0.16
The last step in a proof contains the conclusion.
hope this helps:)
