What is 10 to the 9 th power?

Answer 1

10^9 = 1,000,000,000

The name of which depends upon where you are, and hence which scale you use:

* In those countries that use the long scale (based on power of a million) like Europe:

1,000,000,000 = 1000 x (1000000)^1 = a thousand million or a milliard.

* In those countries that use the short scale (based on powers of a thousand plus one) like USA:

1,000,000,000 = (1000)^(2+1) = a billion.

In the SI (metric) system of prefixes, it is Giga-.
