Example (1):
  Write each of the following in the form av?? where a and b are two
  integers, b is the least possible value:
1) v27
2) 5 v54
3)  3  v2
          3
4)  v84
    v7
Solution:
       1- 3v??
    2- 5 x 3 v?? = 15 v?? =
    3- 3 v?? x          v?? =  v??
               ??          ??
    4-        v????  x  v??  = 2 v??
              v??       v??
