Answer:
N=6
Step-by-step explanation:
You need to prime factorize 150. 150 = 3*5*2*5.
x*x=perfect square.
What we have done so far is we have split 150 into a few digits
You can add 5 to one box and 5 to the other.
Next if we add 3 to one box and 2 to the other box, then they wont be equal.
Let's try 5*6 and 5.
6 is missing from the second box, so N must be 6 to create a perfect square.
The perfect square is 900 and 30*30 = 900, so it is a perfect square.
