Answer 2

Hi Mate !!

Here is your answer :

Question : Solve using suitable identity : 102² - 98².

Solution :

102² - 98² , it is of the form a² - b².

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

102² - 98² , here a = 102 and b = 98.

So,

102² - 98² = ( 102 + 98 ) ( 102 - 98 )

102² - 98² = 200 * 4

102² - 98² = 800.

Hence,

102² - 98² = 800..

Hope it helps you ♥
