$7\sqrt[3] {2x}+3\sqrt[3] {2x^2}$

Work Step by Step

Combine like radicals. In this example, $3\sqrt[3] {2x^2}$ cannot be combined with the other two radicals because they do not share the same radicand. $8\sqrt[3] {2x}+3\sqrt[3] {2x^2}-\sqrt[3] {2x}$ $(8-1)\sqrt[3] {2x}+3\sqrt[3] {2x^2}$ $7\sqrt[3] {2x}+3\sqrt[3] {2x^2}$
