$35 \sqrt[3] {30}$
First of all, in order to make this one large cube root, we multiply the coefficients to obtain that the new coefficient is 35. Recall, $\sqrt[3] a \times \sqrt[3] b = \sqrt[3] {a \times b}$. Thus, we can multiply 10 and 3 to obtain the simplified expression: $35\sqrt[3] {10 \times 3} =35 \sqrt[3] {30}$
