Answer 1

Ответ:

$\frac{ {d}^{7} \times {d}^{13} }{ {d}^{19} } \times \frac{ {y}^{56} \times {y}^{9} }{ {y}^{64} } = \frac{ {d}^{7 + 13} }{ {d}^{19} } \times \frac{ {y}^{56 + 9} }{ {y}^{64} } = \frac{ {d}^{20} }{ {d}^{19} } \times \frac{ {y}^{65} }{ {y}^{64} } = {d}^{20 - 19} \times {y}^{65 - 64} = d \times y$
