★ Solution :-

[tex]\sf \longmapsto 102 \times 98[/tex]

[tex]\sf \longmapsto (a + b)(a - b) = a^2 - b^2[/tex]

Here,

  • a = 100
  • b = 2

[tex]\sf \longmapsto (100 + 2)(100 - 2) = 100^2 - 2^2[/tex]

[tex]\sf \longmapsto 100^2 - 2^2[/tex]

[tex]\sf \longmapsto 10000 - 4[/tex]

[tex]\sf \longmapsto 9996[/tex]

Answer:

9996

Step-by-step explanation:

Algebraic Identity: (a-b)(a+b)=a²-b²

102×98=(100+2)(100-2)

=100²-2²

=10000-4

=9996
