​

Answer 1

$\huge \red{ \sf \: answer}$

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

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

$3 - 8 \times 6 + 15 \times 2 + 15$

$\green{ \bf \: NOW \: APPLY \: BODMAS \: RULE }$

$3 - 48 + 30 + 15$

$48 - 48 = 0$
