Answer 1

Tricks to find square of number .

suppose take 15

divide it in to 2 part

10 and 5

(10 + 5)^2 = 100+ 25 + 100= 225

like that we can solve for 3 digit

105

(100 + 5)^2 = 10^4 + 25 + 1000= 11025

Answer 2

Answer:

Suppose you have to find square of 36

36 = (30+6)

So 36² = (30+6)²

(a + b)² = a² + b² + 2ab

= 30² + 6² + 2(30 × 6)

= 900 + 36 + 360

= 1296
