I do not understand how you get 10000 divided (over) 3010 giving it a result of 1000 divided (over) 301.

We know that change based of log.
Log2 10 written as log10 10 divided by log10 2.
We have a value of log10 2.
So simple calculation.

log(a) X =log X/log a using this formula we can solve.. log(10) 2 = 0.3010.
Using that formula we can write log 2/log 10=0.3010.
So take reciprocal log 10/log 2 = 1/0.3010...use the first line formula log(10) 2 = log 10/log 2 [i.e.log(a) X = log X/log a]=1/0.3010 = 1/3*10power of -4 = 10000/3010 = 1000/301.

0.3010 is in decimals, to remove decimals we add zeros.
