Question :- Find the square :-

(a) 98

(b) 103

(c) 45

(d) 88

Solution :-

a) 98²

→ (100 - 2)²

using (a - b)² = a² - 2ab + b²

→ 100² - 2 * 100 * 2 + 2²

→ 10000 - 400 + 4

→ 9600 + 4

9604 (Ans.)

b) 103²

→ (100 + 3)²

using (a + b)² = a² + 2ab + b²

→ 100² + 2 * 100 * 3 + 3²

→ 10000 + 600 + 9

→ 10000 + 609

10609 (Ans.)

c) 45²

→ (50 - 5)²

using (a - b)² = a² - 2ab + b²

→ 50² - 2 * 50 * 5 + 5²

→ 2500 - 500 + 25

→ 2000 + 25

2025 (Ans.)

d) 88²

→ (100 - 12)²

using (a - b)² = a² - 2ab + b²

→ 100² - 2 * 100 * 12 + 12²

→ 10000 - 2400 + 144

→ 7600 + 144

7744 (Ans.)
