Answer 1

sapose the nomber of row is. x
by the question
x×x=57760

$x = \sqrt{577600}$
x=760

Answer 2

A gardener plants an orchard with 577600 trees and arranges them so that the number of rows of the tree equals the number of tree in each rows.

And, to find the number of rows, we have to find the square root of the number 577600.

Because the number of rows should be equal to number of trees in each row.

Factors of 577600= 2x2x2x2x2x2x5x5x19x19

                   =2x2x2x5x19

                   =8x95

                   =760.

Thus, there are 760 rows.
