Hope you will find my answer in the list of Brainlest!

Rewrite this

$\sqrt{75} = \sqrt[5]{3}$

$\sqrt{18} = \sqrt[3]{2}$

Substitute

$\frac{\sqrt[5]{3} }{\sqrt[3]{2} }$

Rationalise

$\frac{\sqrt[5]{3} }{\sqrt[3]{2} } * \frac{\sqrt[3]{2} }{\sqrt[3]{2} }$

⇒ $\frac{\sqrt[5]{3} \ * \sqrt[3]{2}  }{(\sqrt[3]{2})^2 }$

⇒$\frac{\sqrt[15]{6} }{18}$
