Answer 1

В знаментеле будет a⁻³⁻²=a⁻⁵
a⁻⁶/a⁻⁵=a⁻¹=(2/3)⁻¹=3/2
Ответ 3/2

Answer 2

$\frac{a^{-6}}{a^{-3}*a^{-2}} = \frac{a^{-6}}{a^{-3+(-2)}} = \frac{a^{-6}}{a^{-5}}=a^{-6-(-5)}=a^{-6+5}=a^{-1}= \frac{1}{a}$

$\frac{1}{a} = \frac{1}{ \frac{2}{3} } = \frac{1}{1} : \frac{2}{3} = \frac{1}{1} * \frac{3}{2} = \frac{3}{2} = 1,5$
