Explanation:

Answer 2

Answer: First option.

Explanation:

If the radicals have the same index and the same radicands, they can be added.

Descompose 16 and 54 into their prime factors:

`16=2*2*2*2=2^3*2\\54=2*3*3*3=2*3^3`

Remember that:

`\sqrt[n]{x^n}=x`

Then, rewriting and simpliying, you get:

`=2(\sqrt[3]{16x^3y})+4(\sqrt[3]{54x^6y^5})\\\\=2(\sqrt[3]{2^3*2x^3y})+4(\sqrt[3]{2*3^3*x^6*y^3*y^2})\\\\=2(2x\sqrt[3]{2y})+4(3x^2y(\sqrt[3]{2y^2}))\\\\=4x(\sqrt[3]{2y})+12x^2y(\sqrt[3]{2y^2})`
