Answer:

$\Large{\underline {\underline{\bf{Solutions:-}}}}$

$\sqrt[8]{45} - \sqrt[8]{20} + \sqrt{245} - \sqrt[3]{125} \\ \\ = 8 \times 3\sqrt{5} - 8 \times 2 \sqrt{5} + 7 \sqrt{5} - 3 \times 5 \sqrt{5} \\ \\ = 24 \sqrt{5} - 16 \sqrt{5} + 7 \sqrt{5} - 15 \sqrt{5} \\ \\ = 31 \sqrt{5} - 31 \sqrt{5} \\ \\ = 0$
