# How do you write 70,000 in scientific notation?

Jun 19, 2015

$70000 = 7 \times {10}^{4}$

#### 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 $10$.
