$\sqrt[3]{2/5}$ . $\sqrt[3]{4/25}$  

$\sqrt[3]{2/5 . 4/25}$

$\sqrt[3]{8/125}$

∛8/125 = ∛8/∛125

∛8 = ∛2³ = 2  

∛125 = ∛5³ = 5

∛8/∛125 = 2/5

$\sqrt{5/32}$  :  $\sqrt{2/5}$

$\sqrt{\frac{\frac{5}{32} }{\frac{2}{5} } }$                5/32 ÷ 2/5 = 5/32 × 5/2 = 5·5/32· = 25/64

$\sqrt{\frac{25}{64} }$

√25/√64 = $\frac{5}{8}$

$\frac{\sqrt{\frac{12}{15} .\frac{12}{15} } }{\sqrt[3]{-\frac{1}{64} } }$

12/15 × 12/15 = 4·3/5·3 × 4·3/5·3  = 4/5 ×  4/5  = 4·4/5·5 = 16/25

$\frac{\sqrt{\frac{16}{25} } }{\sqrt[3]{-\frac{1}{64} } }$

$\frac{\sqrt{\frac{16}{25} } }{\frac{1}{8} }$

$\frac{\frac{4}{5} }{\frac{1}{8} }$

- 1/10    -(signo resta)
