What is 4.1 billion in scientific notation?

Answer 1

• In countries that use the long scale (based on powers of a million) like Europe:

4.1 billion = 4.1 x (106)2

= 4.1 x 1012

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

4.1 billion = 4.1 x (103)(2+1)

= 4.1 x 109
