how to calculate 10 to the power 120 easily
Yes but 10^2.08 is not exactly 120
It is 120.226........
10 to the power of any positive whole number is just 1 followed by the index number of zeros
so
10^6 = 1000000
10^2 = 100
etc
10^120= 1 followed by 120 zeros
That's it!!!!!. 1 X 10^120. Unless you want to write a 1 + 120 zeros!!. Or, you want to take the log of 1 X 10^120=120. I'm afraid that's all you can do. You can also write it this way: 10^10^2.08.
