Answer 1

To simplify

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

Now,

$\begin{gathered} \sqrt[]{98}=\sqrt[]{49\times2} \\ =\sqrt[]{7^2\times2} \\ =7\sqrt[]{2} \end{gathered}$

Again,

$\begin{gathered} \sqrt[]{8}=\sqrt[]{4\times2} \\ =\sqrt[]{2^2\times2} \\ =2\sqrt[]{2} \end{gathered}$

Then,

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

So, the simplified form is

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