Question

The value of (369)2 – (368)2 = ?
​

Answer 1

Answer:

Step-by-step explanation:

a^2-b^2=(a+b)(a-b)

(369)^2-(368)^2

=((369+368)(369-368)

=(737)(1)

=737

Answer 2

Answer:

(369)² – (368)²  = 737

Step-by-step explanation:

To find,

(369)² – (368)² =

Recall the formula,

a² - b² = (a+b)(a-b) -----------(1)

Solution:

Substituting the values of a = 369 and b = 368 in equation(1) we get

(369)² – (368)² = (369+368)(369 -368)

(369)² – (368)² = 737 ×1 = 737

∴(369)² – (368)²  = 737
