<h3>Answer:</h3>

\bf 2 \sqrt{10}  \approx6.32456

<h3>Step-by-step explanation:</h3>

\sf  \frac{20}{ \sqrt{10} }

\sf  =  \frac{20}{ \sqrt{10} }  \times  \frac{ \sqrt{10} }{ \sqrt{10} }

\sf  =  \frac{20 \sqrt{10} }{ \sqrt{10} \sqrt{10}  }

\sf  =  \frac{20 \sqrt{10} }{10}

\sf  = 2 \sqrt{10}  \approx6.32456

<h3>Conclusion:</h3>

Simple form of \sf  \frac{20}{ \sqrt{10} } is \bf 2 \sqrt{10}  \approx6.32456.
