#### Answer

(a) 10 to the 2nd power
(b) 10 to the 3rd power

#### Work Step by Step

In (a), the most decimal places that the terms have are two decimal places, so we multiply by 10 to the second power in order to turn them all to integers.
In (b), the most decimal places they have are three, so we multiply by 10 to the third power to turn all of them into integers.
