what is the number 5.1 x 10^7 written in decimal notation

Answer 1

To convert the number \( 5.1 \times 10^7 \) into decimal notation, you move the decimal point in \( 5.1 \) seven places to the right.

Starting with \( 5.1 \):

1. Move the decimal point one place to the right: \( 51.0 \)
2. Move it to the right again: \( 510.0 \)
3. Move it again: \( 5100.0 \)
4. Move it again: \( 51000.0 \)
5. Move it again: \( 510000.0 \)
6. Move it again: \( 5100000.0 \)
7. Move it one more time: \( 51000000.0 \)

So, \( 5.1 \times 10^7 \) written in decimal notation is \( 51000000 \).
