This is a problem where you need to add or subtract to get your answer.
To do this first fill up the 5 and pour it into the 3 until the 3 is full. Now dump the root beer in the 3 out, and pour the remaining root beer in the 5 into the 3. Next fill up the 5 again, and this time pour it into the 3 until the 3 is full. What you have in the 5 is now 4 liters.

Fill up the 5 liters with the unlimited supply. Then fill up the 3 liter with the 5 liter. What's left in the 5 liter must be 2 liters. Dump out the three liter. Pour the 2 liters into the three liter container. Fill the 5 liter again from the unlimited supply. Top off the 3 liter container by adding 1 more liter. This leaves 4 liters in your 5 liter container.
That was fun. Can we do another?

1. fill the 5 liter container (call it A).
2. fill the second container (B) from it. 2 liters will be left in A.
3. Throw out everything from B.
4. Pour the remaining 2 liters from A into B.
5. Fill A with the full 5 liters.
6. B now contains 2 liters. Fill it from A, which will remove 1 liter from A.
7. A has 4 liters.

Fill up the 5 liter container, and pour the 5 liter container into the 3 liter container until the 3 liter container is full. That will leave 2 liters of root beer in the 5 liter container. Repeat twice - get 4 liters.

The key to this is to remember that you can subtract as well as add...
In this case if you fill, the 5L container full, then pour it into the 3L container until it is just full then you will have 2L left in the first container.
Essentially, 5-3=2
Two hints for the final solution.
a) Now, how much space is left in 3L container?
b) how would you use this number to make 4?

Fill the three liter, pour it into the five liter.
Fill the three liter again and pour that into the five liter to the top.
You have 1L left in your three liter.
Dump all the root beer out of the five liter.
Pour the 1L from the three liter into the five liter.
Fill the three liter again and pour into the five liter.
You now have 4L in your five liter!

step 1: fill up the 5L
step 2: fill up the 3L with the 5L. Now you have 2L left in the 5L
step 3: pour away the 3L. Pour the remaining 2L from the 5L into the 3L. Now the 3L is filled 2L
step 4: Fill up the 5L and use it to fill up the remaining 1L of the 3L. Now the 5L is only left with 4L. Done!
