(1) 784
(2) 1764
(3) 9409
(4) 961
(5) 9801
(6) 50625
(7) 99225
(8) 53361
(9) 18225

Answer 1

To find the square root of a number, we start at the end of the number and mark off the pairs of digits by drawing a line above each pair.

(1)784 can be represented as $\overline{7}\overline{84}$

(2) 1764 can be represented as $\overline{17}\overline{64}$

(3) 9409 can be represented as $\overline{94}\overline{09}$

(4) 961 can be represented as $\overline{9}\overline{61}$

(5) 9801 can be represented as $\overline{98}\overline{01}$

(6) 50625 can be represented as $\overline{5}\overline{06}\overline{25}$

(7) 99225 can be represented as $\overline{9}\overline{92}\overline{25}$

(8) 53361 can be represented as $\overline{5}\overline{33}\overline{61}$

(9) 18225 can be represented as $\overline{1}\overline{82}\overline{25}$
