2ⁿ = 20000 → log(2ⁿ) = log(20000) → n log(2) = log(20000) → n = log(20000)/log(2) You can use logs to any base you like as long as you use the same base for each log → n ≈ 14.29

2400000 times 20000 is a mathematical operation, not a rule.
It is: 16400/20000 times 100 = 82%
20000*0.02 or 20000/100*2 = 400
19000 × 20000 = 380,000,000 (three hundred and eighty million)
