Prove that $\sqrt[7]{2}\not\in\mathbb{Q}(\sqrt[7]{3})$

96 Views Asked by At

I need to show that $\sqrt[7]{2}\not\in\mathbb{Q}(\sqrt[7]{3})$ but I have no idea how to do it. I've tried to reason with the extension degrees but I haven't got any satisfactory result.

Could someone help me?

Thanks in advance.
