$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$\frac{7}{ \sqrt{7} }\\$

$= \frac{7}{ \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} }\\$

$= \frac{7 \sqrt{7} }{ \sqrt{7} \times \sqrt{7} }\\$

$= \frac{7 \sqrt{7} }{7}\\$

$(∵ \sqrt{a} \times \sqrt{a} = a)\\$

$= \sqrt{7} \\$
