A) ➡
$= (1025) {}^{2} - (975)1$

$= 1049650$

B)➡

$= (10) {}^{2} + 20 {}^{2}$

$= (10) {}^{2} + (2 \times 10) {}^{2}$

$= 10 {}^{2} + 2 {}^{2} \times 10 {}^{2}$

$= 2 {}^{2} \times 5 {}^{2} \times (1 + 2 {}^{2} )$

$= 4 \times 5 {}^{2} \times (4 + 1)$

$= 4 \times 5 {}^{2} \times 5$

$= 4 \times 5 {}^{3}$

$= 4 \times 125$

$= 500$
