Question

Помогите пожалуйста!!!​

Answer 1

Ответ:

$\frac{ {a}^{ - 5}( {a}^{2} {)}^{8} }{ {a}^{20}( {a}^{ - 2} {)}^{3} } = \frac{ {a}^{ - 5} \times {a}^{16} }{ {a}^{20} \times {a}^{ - 6} } = \frac{ {a}^{ - 5 + 16} }{ {a}^{20 - 6} } = \frac{ {a}^{11} }{ {a}^{14} } = {a}^{11 - 14} = {a}^{ - 3} \\ ( {3}^{ - 1} {)}^{ - 3} = {3}^{ - 1 \times ( - 3)} = {3}^{3} = 27$
