Answer 1

Writing numbers in their Scientific Notations

Answer:

`3.92 * 10^(12)`

Step-by-step explanation:

In writing numbers in their scientific notation, we must first move the decimal point until our number has only a one's digit. From the given number,
`3,920,000,000,000`, it would look like this
`3.92`. Because, we can't fundamentally change the number we need to multiply our new number,
`3.92` with
`10^n` where
`n` is the number of how many times we moved the decimal point to the left. If we moved our decimal to the right,
`n` would be negative. Since we moved it to the left by
`12` times,
`n = 12`.

Now we multiply
`3.92` with
`10^(12)`. It is
`3.92 * 10^(12)`

Answer 2

3.92 X 10^12

Step-by-step explanation:

Writing in scientific notation is writing in power form.

Writing in power form is usually in the form:

X.y × 10ⁿ

Now write 3 920 000 000 000 in this form.

3.92 × 10¹²
