After you reposted, I see the actual question is: 5
. I am going to leave the information below since it will be helpful for you going forward in the class.
5
= 5
= 5
= 5*2*m
= 10m
**********************************
I am going to assume that the problem is actually 
= 
Look for groups of 2 (since it is square root)
= 
Bring ONE of each pair outside the square root and leave the rest inside
= 2 * 2 * 2 * 2 * m 
= 16m
If the question is actually "cubed root" and not square root, then do the same as above except look for groups of 3.

Answer:
16 rows, 8 seedlings left.
Step-by-step explanation:
Divide 200 by 12, since 200 seedlings are going to be split in 12 groups in order to fill the rows.
200 ÷ 12 = 16 with a remainder of 8.
The remainder is basically what is left.
Since 12 seedlings are planted in each row, 8 seedlings is not enough to completely fill the row. So, the answer is 16 rows with 8 seedlings left.
Hope this helped !
