Hii MATE !!

Here is your answer ;

QUESTION : ( 82)² - ( 18)² , Solve USING identities.

Solution :

(82)² - (18)² it is of the form a² - b² .

As we know that , a² - b² = ( a + b ) ( a - b ).

So,

( 82)² - ( 18)² = ( 82 + 18 ) ( 82 - 18 )

(82)² - ( 18)² = 100 × 64

(82)² - (18)² = 6400.

Hence,

(82)² - ( 18)² = 6400.

Hope it helps you ♥
