Question

formula using (a+b)(a-b)=a²-b². simplify 82²-18²​

Answer 1

Answer:

Step-by-step explanation:

IDENTITY :

(A²-B²) = (A+B)(A-B)

HERE;

A = 82

B = 18

THEREFORE;

82²-18²= (82+18)(82-18)

           = 100*64

           = 6400

THEREFORE ;

82²-18²=6,400.

HOPE THIS HELPS.

Answer 2

========================

a²-b² = (a+b) (a-b)

=> 82²-18²​

Here a = 82 , b = 18

=> ( 82 + 18 ) ( 82 - 18 )

=> (100) (64)

=> 6400 is answer
