$0.035$ written in scientific notation is $3.5 \cdot {10}^{-} 2$

#### Explanation:

The scientific notation of a number is such that you write it on the form $m \cdot {10}^{n}$, where $m$ is between 1 and 10.

To get $0.035$ between 1 and 10, we would have to multiply it with $100 = {10}^{2}$. From this we get
$0.035 = 3.5 \cdot {10}^{-} 2$ since we must divide 3.5 on ${10}^{2}$ to get 0.035
