\[\boxed{\mathbf{785\ (785)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)}\ ( - 2)^{2} = - 2 \bullet ( - 2) = 2 \bullet 2 = 4\]

\[( - 2)^{3} = - 2 \bullet ( - 2) \bullet ( - 2) = 4 \bullet ( - 2) = - 8\]

\[( - 2)^{4} = ( - 2)^{3} \bullet ( - 2) = - 8 \bullet ( - 2) = 16\]

\[( - 2)^{5} = ( - 2)^{4} \bullet ( - 2) = 16 \bullet ( - 2) = - 32\]

\[\textbf{б)}\ ( - 3)^{2} = ( - 3) \bullet ( - 3) = 3 \bullet 3 = 9\]

\[( - 3)^{3} = ( - 3)^{2} \bullet ( - 3) = 9 \bullet ( - 3) = - 27\]

\[( - 3)^{4} = ( - 3)^{3} \bullet ( - 3) = - 27 \bullet ( - 3) = 27 \bullet 3 = 81\]

\[\textbf{в)}\ ( - 5)^{2} = - 5 \bullet ( - 5) = 5 \bullet 5 = 25\]

\[( - 5)^{3} = ( - 5)^{2} \bullet ( - 5) = 25 \bullet ( - 5) = - 125\]

\[( - 5)^{4} = ( - 5)^{3} \bullet ( - 5) = - 125 \bullet ( - 5) = 125 \bullet 5 = 625\]

\[\textbf{г)}\ ( - 1)^{2} = - 1 \bullet ( - 1) = 1 \bullet 1 = 1\]

\[( - 1)^{3} = ( - 1)^{2} \bullet ( - 1) = 1 \bullet ( - 1) = - 1\]

\[( - 1)^{4} = ( - 1)^{3} \bullet ( - 1) = - 1 \bullet ( - 1) = 1 \bullet 1 = 1\]

\[( - 1)^{5} = ( - 1)^{4} \bullet ( - 1) = 1 \bullet ( - 1) = - 1\]
