\sqrt[]{98\text{ }}+\sqrt[]{8}

Expanding the expressions,


\sqrt[]{49\cdot2}\text{ +}\sqrt[]{2\cdot2\cdot2}
\sqrt[]{7^2\cdot2}\text{ + }\sqrt[]{2^3}
\sqrt[]{7^2}\text{ }*\sqrt[]{2}\text{ +}\sqrt[]{2^2}\text{ }*\sqrt[]{2}
\begin{gathered} 7*\sqrt[]{2}\text{ +2}*\sqrt[]{2} \\ 7\sqrt[]{2}\text{ + 2}\sqrt[]{2} \\ =9\sqrt[]{2} \end{gathered}

Hence, in the boxes where you have the term missed, the correct answer to put there is:


\sqrt[]{7^2\text{ }}\text{not }\sqrt[]{7}
