Answer 1

Explicación paso a paso:

$8ab + 3xy$

$8(2)(1) + 3(3)(5)$

$16 + 45$

$61$

__________________________

$4x - 2xy + 10$

$4(3) - 2(3)(5) + 10$

$12 - 30 + 10$

$22 - 30$

$- 8$

__________________________

$12 {a}^{2} + 4ab + {x}^{3} {y}^{2}$

$12(2) {}^{2} + 4(2)(1) + (3) {}^{3} (5) {}^{2}$

$12(4) + 8 + (27)(25)$

$48 + 8 + 675$

$731$
