por favor explique com os cálculos por gentileza​

Answer 1

Resposta:

$\frac{ {x}^{4} - {y}^{4} }{ {x}^{3} - {x}^{2}y + x {y}^{2} - {y}^{3} } \\ \\ \\ \frac{ {111}^{4} - {112}^{4} }{ {111}^{3} -{111}^{2} \times 112+111\times{112}^{2} -{112}^{3} } =$

$\frac{ - 5544895}{1355310 \times 112 + 111 \times {112}^{2} - {112}^{3} } \\ \\ \\ \frac{ - 5544895}{151794720 + 111 \times 12544 - 1404928} \\ \\ \\ \frac{ - 5544895}{151794831 \times 12544 - 1404928} = \\ \\ \\ \frac{ - 5544895}{153187104 - 1404928} = \\ \\ \\ \frac{ - 5544895}{151782176} =$
