Question

Using the formula(a^2)=a^2+b^2+2ab . Evaluate (508)^2

Answer 1

Given

Using identity solve this question

(508)²

Solution

Solve this by applying identity

✞ Identity : (a + b)² = a² + b² + 2ab

→ (500 + 8)²

→ (500)² + (8)² + 2 × 500 × 8

→ 2500 + 64 + 8000

→ 10564

Some identities

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a² - b² = (a + b)(a - b)

Answer 2

Answer:

Given

Using identity solve this question

(508)²

Solve this by applying identity

✞ Identity : (a + b)² = a² + b² + 2ab  

→ (500 + 8)²  

→ (500)² + (8)² + 2 × 500 × 8  

→ 2500 + 64 + 8000  

→ 10564

Some identities

(a + b)² = a² + b² + 2ab

(a - b)² = a² + b² - 2ab

a² - b² = (a + b)(a - b)
