Perfect Squares and Long Division

The video tutorial addresses a word problem involving perfect squares. It begins by explaining the task of finding the least number that must be added to 1300 to make it a perfect square and determining the square root of the resulting number. The tutorial uses the long division method to check if 1300 is a perfect square, revealing it is not. It then calculates the next perfect square, 1369, and determines that adding 69 to 1300 achieves this. The square root of 1369 is identified as 37, providing a complete solution to the problem.
