10 000 000 000 000 000 000 000 000 000 American name Ten octillion or European Name Ten quadrilliard
10 000 000 = 10 to the power of 7

100, 000, 000 * 10, 000 = 1, 000, 000, 000
In the United States (but not in England) we use these words: ten trillion * * * * * Not so. In the UK since the middle 1960s, a billion has officially been a thousand million - not a million million. So the above number IS ten trillion.

Next power of 10 after 10 000 is 100 000.
10-21 = 0.000 000 000 000 000 000 001
I'm guessing that is: (70 000 000)² = (7×10^7)^2 = (7×10^7) × (7×10^7) = (7×7)×(10^7 × 10^7) = (7×7)×10^(7+7) = 49×10^14 = 4 900 000 000 000 000
