Пошаговое объяснение:
[tex] {a}^{6} \times {( {a}^{ - 2} )}^{4} = {a}^{6} \times {( \frac{1}{ {a}^{2} } )}^{4} [/tex]
[tex] {a}^{6} \times \frac{1}{ {a}^{2 \times 4} } = \frac{ {a}^{6} }{ {a}^{8} } = \frac{1}{ {a}^{2} } [/tex]
При а = 1/7:
[tex] \frac{1}{ {( \frac{1}{7} )}^{2} } = \frac{1}{ \frac{1}{49} } = 49[/tex]
