The solution is given below

$= > (98 \times 98) \\ = > (98) \times (98) \\ = > (100 - 2) \times (100 - 2) \\ = > (100 - 2) {}^{2} \\ = > use \: the \: identity \: (x - y) {}^{2} = {x}^{2} + y {}^{2} - 2xy \\ = > so \\ = > {100}^{2} + {2}^{2} - 2 \times 100 \times 2 \\ = > 10000 + 4 - 400 \\ = > 10000 - 396 \\ = > 9604$

So the answer is 9604❤❤✏✏
