The amount of water at the Georgia Aquarium is 2 * 10¹ times greater than the aquarium of the Americas hold.
<h3>How to work with scientific notation of numbers?</h3>
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
We are given that the tanks at the Georgia Aquarium hold approximately 8.4 × 10⁶ gallons of water.
Meanwhile, the tanks at the Audubon Aquarium of the Americas hold about 400,000 gallons of water.
Thus, to estimate how many times as great the amount of water is at the Georgia Aquarium, we will divide as;
(8.4 × 10⁶)/(400000)
Converting 8.4 × 10⁶ to normal number gives;
8400000
Thus;
(8.4 × 10⁶)/(400000) = 8400000/400000
= 21
Thus, writing in scientific notation gives;
2.1 * 10¹ approximately 2 * 10¹
