Answer 1

Answer:

In this method, first find the unit digit of square root from the unit digit of given number using the following table. Discard the last two digits and then check between which two squares the remaining numbers lie.

Step-by-step explanation:

Solution :

Unit digit of 256 = 6

∴ unit digit of square root = 4 or 6

Discard 56, digit remain is 2.

1 2 < 2 < 2 2

So 256 must be 14 2 or 16 2

As we know that 15 2 = 225 so,

√ 256 = 16.
