Question

How do you write 810,000 in scientific notation?

Answer 1

`8.1 xx 10^5`

Explanation:

Count the number of times you need to shift the number to the right before it's less than `10`. This gives you the exponent.

If you started with a number less than `1` then count the number of times you need to shift it to the left before it's greater than or equal to `1`.

For example, `0.0023 = 2.3 xx 10^(-3)`
