Answer 1

Answer:

0

Step-by-step explanation:

4√81 – 8(3√216 + 15(5√32) + √225   plez tell me the answer

ANSWER

We need to simplify, so  we get

4√81 – 8(3√216 + 15(5√32) + √225

$\sqrt[4]{81} - 8\times\sqrt[3]{216} + 15\times\sqrt[5]{32} + \sqrt{225} \\ \\= \sqrt[4]{3^4}- 8\times\sqrt[3]{6^3} + 15\times\sqrt[5]{2^5} + \sqrt{15^2} \\ \\= 3 - 8\times6 + 15\times2 + 15 \\ \\= 3 - 48 + 30 + 15 \\ \\= 48 - 48\\ \\= 0$

Answer 2

Answer:

$\sqrt[4]{81}- 8\times\sqrt[3]{216}+ 15\times\sqrt[5]{32}+\sqrt{225} = 0$

Step-by-step explanation:

√814-8√2163+15√325+√225

$\sqrt[4]{81} - 8\times\sqrt[3]{216} + 15\times\sqrt[5]{32} + \sqrt{225} \\ \\= \sqrt[4]{3^4}- 8\times\sqrt[3]{6^3} + 15\times\sqrt[5]{2^5} + \sqrt{15^2} \\ \\= 3 - 8\times6 + 15\times2 + 15 \\ \\= 3 - 48 + 30 + 15 \\ \\= 48 - 48\\ \\= 0$
