We find its logarithm base 10, which we have access to on most every calculator,
whether graphing or only scientific.



That means that 21000 is approximately equal to 10301.0299957

Then 10301.02999566398 = 10301100.02999566398 = 10301(1.0715086071833) = 

1.0715086071833 × 10301.

That's the scientific notation for 21000
If we moved the decimal 301 places to the right the number would have 302
digits.
