How many perfect squares are there in between 5000 and 8000.
(Ex. 4 is the perfect sq of 2)

• 70^2=4900
  71^2= 5041
  sq root of 8000 = 89.44
  89^2= 7921
  
  so perfect square numbers between 5000 and 8000 are squares of 71,72,.... 89
  
  so 19 numbers.

• 70^2 = 4900
  71^2 = 5181
  89^2 = 7821
  90^2 = 8100
  
  THUS ALL THE SQUARES OF NUMBERS BETWEEN 71 AND 89 FALL IN THE GIVEN RANGE
