#### Explanation:

Make sure you move your decimal to where your number will be between 1 and 10. Then if you moved your decimal to the left, your exponent for 10 will increase for each place you moved it; if you moved your decimal to the right, your exponent for 10 will decrease for each place you moved it.

*twice* to the left in order for it to be in between 1 and 10.
