goldfiish [28.3K]

To solve the problem we must know about Scientific notations.

<h2>Scientific notations</h2>

The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

The number of 221,000,000,000,000,000,000 can be represented as 2.21e+21.

<h2>Explanation</h2>

Given to us

  • 221,000,000,000,000,000,000

The above number can be written as 2.21e+21.

As in scientific notations, the number between 1 and 10 can only be represented, therefore, the number can be only 2.21e+21.

Hence, the number of 221,000,000,000,000,000,000 can be represented as 2.21e+21.
