= ³√421.875

[tex] = \sqrt[3]{3 {}^{3} \times 5 {}^{6} }[/tex]

[tex] = \sqrt[3]{3 {}^{3} } \sqrt[3]{5 {}^{6} } [/tex]

[tex] = 3 {}^{ \frac{3}{3} } \sqrt[3]{5 {}^{6} } [/tex]

[tex] = 3 {}^{ \frac{3}{3} } \times 5 {}^{ \frac{6}{3} } [/tex]

[tex] = 3 {}^{1} \times 5 {}^{ \frac{6}{3} } [/tex]

[tex] = 3 {}^{1} \times 5 {}^{2} [/tex]

[tex] = 3 \times 5 {}^{2} [/tex]

[tex] = 3 \times 25[/tex]

= 75

Maka hasil akar pangkat 3 dari 421.875 adalah 75 ✓

[tex] \sqrt[3]{421.875} = [/tex]

[tex] = \sqrt[3]{ {75}^{3} } [/tex]

[tex] = {75}^{ \frac{3}{3} } [/tex]

[tex] = {75}^{1} [/tex]

[tex] = 75[/tex]
