Answer 1

we are to simplify

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

SOLUTION

$\begin{gathered} \sqrt[]{98}\text{ + }\sqrt[]{8} \\ =\text{ }\sqrt[]{7^2\text{ }\times2}\text{ }+\sqrt[]{2^3} \\ =\text{ }\sqrt[]{7^2}\sqrt[]{2}\text{ +}\sqrt[]{2^2}\sqrt[]{2} \\ =7\sqrt[]{2}\text{ + 2}\sqrt[]{2} \end{gathered}$

Therefore the answer is

$7\sqrt[]{2}\text{ + 2}\sqrt[]{2}$
