Question

How do you write 70,000 in scientific notation?

Answer 1

`70000 = 7 xx 10^4`

Explanation:

Count the number of times that you need to divide the number by `10` until you get a number that is less than `10`. That count gives you the exponent - the power of `10`.

Dividing by `10` is basically shifting the number one digit position to the right, so count the number of times you need to do that, to get a mantissa less than `10`.
