Вычислите значение выражения y^3 при y=5; 0,1; -3; -1/4.

\[y^{3}\]

\[y = 5:\]

\[5^{3} = 5^{2} \cdot 5 = 25 \cdot 5 = 125.\]

\[y = 0,1:\]

\[{0,1}^{3} = 0,001.\]

\[y = - 3:\]

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

\[= - 9 \cdot 3 = - 27.\]

\[y = \ - \frac{1}{4}:\]

\[\left( - \frac{1}{4} \right)^{3} = - \left( \frac{1}{4} \right)^{3} = - \frac{1}{4^{3}} =\]

\[= - \frac{1}{4^{2} \cdot 4} = - \frac{1}{16 \cdot 4} = - \frac{1}{64}.\]
