$\sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} \: + \sqrt{225}$

$= \sqrt[4]{3 \times 3 \times 3 \times 3 \: } \\ \: \: \: \: - 8 \times \sqrt[3]{6 \times 6 \times 6 \: } \\ \: \: \: \: + 15 \sqrt[5]{2 \times 2 \times 2 \times 2 \times 2} \\ \: \: \: \: + \sqrt{15 \times 15}$

= 3 - 8 x6 + 15 x 2 + 15

= 3- 48 + 30 + 15

= -45 + 45

= 0
