What is 3 to the millionth power?

It would take a much bigger computer than the one we have here to calculate

that number exactly. We can estimate it like this:

log (31,000,000) = 1,000,000 log(3) = 1,000,000 (0.477121254) = 477,121.254

31,000,000 = 10477,121.254 = 1.795 x 10477,121 (rounded)

That's 1795 followed by 477,118 zeros.

If we leave out all the commas and write 5 digits in every inch of paper,

then the number is 11/2 miles long.
