Dec 28, 2015

$6.5 \cdot {10}^{-} 6$

#### Explanation:

To make a value into scientific notation, always set the value to ones digit ( not 0) and the rest are decimals, then count the number of places it moved, to determine its sign, going right is positive and going left is negative and the will be the expinent for the ${10}^{x}$

For our example

$0.0000065$
Make it in ones place,
6.5
Then count the number of decimal place it will move to become the original value,
In this case its 6 decimal place to the right, so -6

Thus $6.5 \cdot {10}^{-} 6$
