Question

3√3375 + 3√-2744 + 3√729​

Answer 1

Question

$\tt{\sqrt[3]{3375} + \sqrt[3]{-2744}+\sqrt[3]{729}}$

Solution

$\tt{→\sqrt[3]{3375} + \sqrt[3]{-2744}+\sqrt[3]{729}}$

$\tt{→\sqrt[3]{3³×5³} + \sqrt[3]{-(2³×7³}+\sqrt[3]{3⁶}}$

$\tt{→\sqrt[3]{15³} + \sqrt[3]{-(14)³}+\sqrt[3]{3⁶}}$

$\tt{→15 -14+3²}$

$\tt{→15 -14+9}$

$\tt{→24 -14}$

$\tt{→10}$
