Question

The power of 10 is the ________________ of places we move the decimal point to get the first factor. For any number greater than ______, the power of 10 in scientific notation will be (positive or negative?).

First_______ Power of_____

Example: Let’s look at the mass of Earth in kilograms.
What power?____
Numbers can also be converted from scientific notation to standard notation.
Look at the number 6.51 × 108 . The power of 10 denotes the ________________ of places the ________________ ________________ has to move. The power of 10 in this number is positive, so we move the decimal point to the (left or right?) 8 places.
The number 6.51 × 108 written in standard notation is ______________________.

Answer 1

Explanation:

The power of 10 is the exponent of places we move the decimal point to get the first factor. For any number greater than 1, the power of 10 in scientific notation will be positive.

First Non-zero Power of 10

Example: Let’s look at the mass of Earth in kilograms.

What power? 9

Numbers can also be converted from scientific notation to standard notation.

Look at the number 6.51 × 108 . The power of 10 denotes the number of places the decimal point has to move. The power of 10 in this number is positive, so we move the decimal point to the right 8 places.

The number 6.51 × 108 written in standard notation is 651000000.
