Question

A gardner has 6412 plants . He wants to plant these in such a way that rhe number of rows and number of columns remain the same . Find the minimum number of plants he needs more for this

Answer 1

Answer : we have number of plants 6412 ,

So take prime factor of number so we got the pairs of plants .

6412 = direct nearest value 80^2 (6400) so its not a perfect square

81^2 = 6561

So 6561 - 6412 = 149

149 trees are required for same rows and columns
