Explanation

When you split the number 856,000,000,000 into a **coefficient** and a **power of 10 **you do get 856 billion in exponential form, but there is an indefinite number of possibilities.

As you probably want 856 billion in *normalized* scientific notation, the coefficient or significand of 856,000,000,000 must be in the interval **[1,10[**.

In other words, the coefficient has to be equal to or greater than 1 (≥1), and less than 10 (<10).

In this post we mean 856 billion in the *normalized* version, unless stated otherwise.

Not a convention, but this reflects the use of the term in daily life.

Therefore:

This can also be expressed as \(8.56 \times 10^{11}\) , using the caret symbol, or as 8.56e+11, which is called 856 billion in e-notation, further discussed in the section ahead.
