Question

How do you write `27.1times10^4` in scientific notation?

Answer 1

`2.71 xx 10^5`

Explanation:

Since scientific notation requires a single integer on the left side of the period, just move the decimal over one place to the left.

This will add one to the exponent, making it a 5. This is due to the decimal being moved over 5 spaces to the left from the end of the original number (271,000).
