Answer 1

Answer:

125

Step-by-step explanation:

By Estimation ,

Group      1         2

              157     625

in group 2 ,

unit's place digit = 5

5^2 = 25

∴ the unit's place digit of required no. is 5

In group 1 ,

144 < 157 < 169

$12^{2}$ < 157 < $13^{2}$

12 < $\sqrt{157}$ < 13

∴ the required no. is 125.
