Вычислите:
а) $231 + 12^2$;
б) $(9 + 17)^2$;
в) $312 - 17^2$;
г) $(914 - 896)^2$;
д) $18^2 + 12^2$;
е) $10^3 + 10^2$.
$231 + 12^2 = 231 + 144 = 375$
$\snippet{name: column_multiplication, x: 12, y: 12}$
$(9 + 17)^2 = 26^2 = 676$
$\snippet{name: column_multiplication, x: 26, y: 26}$
$312 - 17^2 = 312 - 289 = 23$
$\snippet{name: column_multiplication, x: 17, y: 17}$
$(914 - 896)^2 = 18^2 = 324$
$\snippet{name: column_multiplication, x: 18, y: 18}$
$18^2 + 12^2 = 324 + 144 = 468$
$10^3 + 10^2 = 1000 + 100 = 1100$
