the operation:

2*10^1 - 4*10^0 = 20 - 4 = 16

Gives a square number.

<h3>How to get a perfect square?</h3>

A perfect square is the product of a number and itself.

As you can see in the example, 16 is a square number. Then let's try to get 16.

To get 16 we can use the difference:

20 - 4

So the first therm needs to be equal to 20, and the second equal to 4.

To write 20 in scientific notation we have:

2*10^1

To write 4 in in scientific notation:

4*10^0

Then the operation:

2*10^1 - 4*10^0 = 20 - 4 = 16

Gives a square number.

You have to divide the amount of money by the pack number. So A would be 0.25 cents per soda. B would be 0.25 cents per soda. C would be 0.26 cents per soda. And finally, D would be 0.22 cents per soda. Therefore Store D would be the best buy.
