Answer :
21
Step-by-step explanation:
65856 can be written as 7 × 7 × 7 × 3 × 2 × 2 ×2 × 2 × 2 ×2
The numbers which remained are 7 and 3 as they are not having another number to be divided when square root is formed .
So we have to divide 65856 by 7 × 3 to make it a perfect square .
So , 65856 ÷ 21 = 3136
Square root of 3136 = 56
