Question

evaluate 3√27 + 3√o.oo8 +3√o.o64

Answer 1

Answer:

$Value \: of \: \sqrt[3]{27}+\sqrt[3]{0.008}+\sqrt[3]{0.064}= 3.6$

Step-by-step explanation:

$Value \: of \: \sqrt[3]{27}+\sqrt[3]{0.008}+\sqrt[3]{0.064}\\=\sqrt[3]{3\times 3\times 3}+\sqrt[3]{0.2\times 0.2\times 0.2}+\sqrt[3]{0.4\times 0.4\times 0.4}\\=\sqrt[3]{3^{3}}+\sqrt[3]{(0.2)^{3}}+\sqrt[3]{(0.4)^{3}}\\=3+0.2+0.4\\=3.6$

Therefore,

$Value \: of \: \sqrt[3]{27}+\sqrt[3]{0.008}+\sqrt[3]{0.064}= 3.6$
