# How do you write 9.87 times 10^5 in decimal notation?

Nov 22, 2015

987000.0

#### Explanation:

The decimal place stays where it is and the numbers moves to the left 5 times. You have to use zeros as place holders. When people say "put zeros on the end" they are very wrong!!!!!!

Consider $0.25 \times 10$.

If you put a zero on the end you get: $0.250$ which is no different in value.

Move the number 1 place to the left however and you get $2.5$ which is correct.
