Question

using suitable identity find: (231)^2-(131)^2​

Answer 1

Answer:

36200

Step-by-step explanation:

By using identity (a²-b²)= (a-b) (a+b)

(231)²-(131)²= (231-131) (231+131)

= (100) (362)

= 36200

Answer 2

Answer:

We have,

(231)^2-(131)^2

: Using Identity (a)^2-(b)^2 = (a+b)(a-b)

:(231+131)(231-131)

:362.100
