How do you write 1.54 trillion in scientific notation?

Answer 1

• As I use the long scale (based on powers of a million, and used in countries like Europe), I write it as:

1.54 trillion = 1.54 x 1018

• Others, however, use the short scale (based on powers of a thousand, and used in countries like USA) and so write it as:

1.54 trillion = 1.54 x 1012
