Answer 1

we are to simplify

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

SOLUTION

`\begin{gathered} \sqrt[]{98}\text{ + }\sqrt[]{8} \\ =\text{ }\sqrt[]{7^2\text{ }*2}\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}`
