Given information: An expression is given as $\sqrt{80{s}^{15}}$ .

Calculations: We have been given an expression is$\sqrt{80{s}^{15}}$ .

To simplify the radical expressions by using absolute value as needed, we must know about the radical properties and the index value of root is even or odd as shown below:

We know that,$\left(ab\right)}^{m}={a}^{m}\cdot {b}^{m$ and the corresponding product property of radical expression is $\sqrt{n}\left\{ab\right\}=\sqrt{n}\left\{a\right\}\cdot \sqrt{n}\left\{b\right\}$ .

$\Rightarrow \sqrt{80{s}^{15}}$ [Simplify the square root of $80{s}^{15}$ with radical properties]

$\Rightarrow \sqrt{16{s}^{14}\cdot 5s}$ [Rewrite $80{s}^{15}=16{s}^{14}\cdot 5s$ ]

$\Rightarrow \sqrt{16{s}^{14}}\cdot \sqrt{5s}$ [By using radical property $\sqrt{n}\left\{ab\right\}=\sqrt{n}\left\{a\right\}\cdot \sqrt{n}\left\{b\right\}$ ]

$\Rightarrow 4\left|{s}^{7}\right|\sqrt{5s}$ [$\sqrt{n}\left\{{a}^{n}\right\}=\left|a\right|$ , if the value of index is even]

Hence, the simplification of$\sqrt{80{s}^{15}}\text{}is\text{}4\left|{s}^{7}\right|\sqrt{5s}$
