Abc = 19944
3.(abc) = 3.(19944)
3c.a.b = 59832
(a).a.(a) = 59832
a³ = 59832
a = 6 \sqrt[3]{277}

a = b = 6 \sqrt[3]{277}

3c = a ====>  c =  \frac{a}{3}

c =  \frac{6 \sqrt[3]{277} }{3}

c = 2. \sqrt[3]{277}

2a + b - c = ? 
2.(6 \sqrt[3]{277} ) + 6. \sqrt[3]{277} - 2. \sqrt[3]{277} 16. \sqrt[3]{277}
