Question

Find the value of 369 square - 368 square using suitable identity

Answer 1

Answer:

$(369)^{2} - (368)^{2} \\ = (369 + 368)(369 - 368) \\ = 737 \times 1 \\ = 737$

Answer 2

Answer:

369² - 368² = 737

Step-by-step explanation:

we need to find

369² - 368²

we will use here

a² - b² = (a + b) ( a - b)

taking a = 369

b = 368

369² - 368²

= (369 + 368) (369 - 368)

= 737 * 1

= 737

369² - 368² = 737

another method

369² - 368²

= (368 + 1)² - 368²

using (a + b)² = a² + b² + 2ab

a = 368 , b = 1

= 368² + 1² + 2(368)(1) - 368²

= 1 + 736

= 737
