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.

We know,
loga M= logb M ÷ logb a,
so, log2 10= log10 10 ÷ log10 2 [here b= 10],
=1 ÷ 0.3010,
=10000 ÷ 3010,
=1000/301.

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