60 soldiers are left out.
∴Remainaing soldiers = 8160 − 60 = 8100
The number of soldiers in each row to form a perfect square would be the square root of 8100. We have to find the square root of 8100 by the long division method as shown below:
Hence, the number of soldiers in each row to form a perfect square is 90.
