#### Explanation:

The scientific notation format consists of expressing a number (normally a measurement) between 1 and 10 and then multipliying it by a whole number power of 10.

To decide on the number of digits included, find the number of significant figures present in the given number.

Note that the trailing zeros are not significant. This leaves your number with 3 significant figures.

This means three digits are needed in your scientific notation expression.
