What numbers multiply to equal 50?
I chose 5x10
5 is prime but 10 is not. So I have to continue until all numbers (ends of the branches) are prime.
16
If there are pairs,
Circle them.
The square root of 5x5(25) is 5
That number goes outside the radical
17
Single numbers
Stay under the radical.
if there is more than one, multiply them together and put under radical.
18
Here is a more involved example
The prime numbers we have are 3,3,2,5.
The 3 will go to the outside of radical. The leftover 2 & 5 will be multiplied and left under the radical.
