Answer 1

Notice that:

`\begin{gathered} 36=6^2, \\ 64=8^2, \\ 225=15^2, \\ 169=13^2\text{.} \end{gathered}`

Therefore:

`\begin{gathered} \sqrt[]{36}=6, \\ \sqrt[]{64}=8, \\ \sqrt[]{225}=15, \\ \sqrt[]{169}=13. \end{gathered}`

Answer:

`\begin{gathered} \sqrt[]{36}=6, \\ \sqrt[]{64}=8, \\ \sqrt[]{225}=15, \\ \sqrt[]{169}=13. \end{gathered}`
