==================================================
Cube root of 76.25
 = \sqrt[3]{76.25}

 = \sqrt[3]{ \frac{305}{4} } = \frac{ \sqrt[3]{305} }{ \sqrt[3]{4} }

 = \frac{ \sqrt[3]{305 \times 4 {}^{2} } }{4} = \frac{ \sqrt[3]{305 \times 16} }{4}

 = \frac{2 \sqrt[3]{305 \times 2} }{4}

 \frac{ \sqrt[3]{305 \times 2} }{2}

 = \frac{ \sqrt[3]{610} }{2}
___________________________________________
Cube root of 37.62
 = \sqrt[3]{37.62}

 = \sqrt[3]{ \frac{1881}{50} } = \frac{ \sqrt[3]{1881} }{ \sqrt[3]{50} }

 = \frac{ \sqrt[3]{1881 \times 50 {}^{2} } }{50} = \frac{ \sqrt[3]{1881 \times 2500} }{50}

 = \frac{5 \sqrt[3]{1881 \times 20} }{50} = \frac{5 \sqrt[3]{1881 \times 20} }{10}

 = \frac{ \sqrt[3]{37620} }{10}
_________________________________________
Cube root of 458
 = \sqrt[3]{458}

 \sqrt[3]{458} = congruent \: 7.70824
_________________________________________
Cube root of 732
 \sqrt[3]{732} = <br />congruent \: 9.01233
