Question

a) 

b) 

Answer 1

a) 0

b)-3

Answer 2

a) \(\sqrt[3]{27}-\sqrt[3]{-8}-\sqrt[3]{125}=\sqrt[3]{3^3}+\sqrt[3]{2^3}-\sqrt[3]{5^3}=3+2-5=0\)

b) \(\frac{\sqrt[3]{135}}{\sqrt[3]{5}}-\sqrt[3]{54}.\sqrt[3]{4}=\sqrt[3]{\frac{135}{5}}-\sqrt[3]{54.4}=\sqrt[3]{27}-\sqrt[3]{216}=3-6=-3\)

Answer 3

a) \(\sqrt[3]{27}=3\)

\(\sqrt[3]{-8}=-2\)

\(\sqrt[3]{125}=5\)

=> 3 \(-\) -2 - 5 = 0
