Answer 2

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (102) {}^{2}$

$\sf \pink{using \: (a + b) {}^{2} = {a} {}^{2} + {b}^{2} + 2ab}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (100 + 2) {}^{2}$

$: ⟹ {(100)}^{2} + {(2)}^{2} + 2(100)(2)$

$\: \: : ⟹ \: \: \: \: 10000 + 4 + 400$

$\: \: \: \: \: : ⟹ \: \: \: \: \: \: \: \: \: 10404$
