Step-by-step explanation:

★ Solution :-

[tex]\sf \longmapsto 98^2[/tex]

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

Here,

  • a = 100
  • b = 2

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

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

[tex]\sf \longmapsto 10000 - 400 + 4[/tex]

[tex]\sf \longmapsto 9606[/tex]
