​

Answer 1

Answer:

0

Step-by-step explanation:

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

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

$(3) - 8(6) + 15(2) + 15$

$3 - 48 + 30 + 15$

$30 + 15 + 3 - 48$

$48 - 48$

$= 0$
