Soalan 1:
Salin dan lengkapkan setiap yang berikut.
Penyelesaian:
(a)
$$ \begin{aligned} & 8 \times 8 \times 8=512 \\ & \sqrt[3]{512}=\sqrt[3]{8 \times 8 \times 8} \\ &=8 \end{aligned} $$
(b)
$$ \begin{aligned} & 0.3 \times 0.3 \times 0.3=0.027 \\ & \begin{aligned} \sqrt[3]{0.027} & =\sqrt[3]{0.3 \times 0.3 \times 0.3} \\ & =0.3 \end{aligned} \end{aligned} $$
(c)
$$ \begin{aligned} \left(-\frac{1}{2}\right)^3 & =-\frac{1}{8} \\ \sqrt[3]{-\frac{1}{8}} & =\sqrt[3]{\left(-\frac{1}{2}\right)^3} \\ & =-\frac{1}{2} \end{aligned} $$
