Answer 1

To simplify

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

Now,

`\begin{gathered} \sqrt[]{98}=\sqrt[]{49*2} \\ =\sqrt[]{7^2*2} \\ =7\sqrt[]{2} \end{gathered}`

Again,

`\begin{gathered} \sqrt[]{8}=\sqrt[]{4*2} \\ =\sqrt[]{2^2*2} \\ =2\sqrt[]{2} \end{gathered}`

Then,

`\begin{gathered} \sqrt[]{98}+\sqrt[]{8}=7\sqrt[]{2}+2\sqrt[]{2} \\ =9\sqrt[]{2} \end{gathered}`

So, the simplified form is

`7\sqrt[]{2}+2\sqrt[]{2}=9\sqrt[]{2}`
