Simplify the square root. Assume all variables represent positive numbers. If the square root is already simplified, so state.

Answer 1

`7\sqrt[]{2}`

Explanation:

We have the following square root:

`\sqrt[]{98}_{}`

We check if we can simplify:

`\begin{gathered} 98=49\cdot2=7^2\cdot2 \\ \sqrt[]{7^2\cdot2}=7\sqrt[]{2} \end{gathered}`
