Writing numbers in their Scientific Notations
Answer:
[tex]3.92 \times 10^{12}[/tex]
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, [tex]3,920,000,000,000[/tex], it would look like this [tex]3.92[/tex]. Because, we can't fundamentally change the number we need to multiply our new number, [tex]3.92[/tex] with [tex]10^n[/tex] where [tex]n[/tex] is the number of how many times we moved the decimal point to the left. If we moved our decimal to the right, [tex]n[/tex] would be negative. Since we moved it to the left by [tex]12[/tex] times, [tex]n = 12[/tex].
Now we multiply [tex]3.92[/tex] with [tex]10^{12}[/tex]. It is [tex]3.92 \times 10^{12}[/tex]
