Answer:

\text{The value of }(a+b+c)^3\text{ is }27abc

Step-by-step explanation:

Given that

\sqrt[3]{a}+\sqrt[3]{b}+\sqrt[3]{c}=0\

\text{we have to find the value of }(a+b+c)^3

As we know

x^3+y^3+z^3=(x+y+z)(x^2+y^2+z^2-xy-yz-xz)+3abc

If x+y+z=0, then

x^3+y^3+z^3=3xyz

Put\thinspace x=\sqrt[3]{a}, y=\sqrt[3]{b}, z=\sqrt[3]{c}\

Then, we get

(\sqrt[3]{a})^3+(\sqrt[3]{b})^3+(\sqrt[3]{c})^3=3(\sqrt[3]{a})(\sqrt[3]{b})(\sqrt[3]{c})

a+b+c=3(\sqrt[3]{a})(\sqrt[3]{b})(\sqrt[3]{c})

Take cube on both sides

(a+b+c)^3=27(\sqrt[3]{a})^3(\sqrt[3]{b})^3(\sqrt[3]{c})^3=9abc

\text{Hence, the value of }(a+b+c)^3\text{ is }27abc
