(ii) 2

Step-by-step explanation:

(i)

$x^3+y^3=(2)^3+(8)^3=8+512=520$

(ii)

$\sqrt[3]{y}=\sqrt[3]{8}=2$

Hope this helps!

Answer 2

Answer:

(i) 520

(ii) 2

Step-by-step explanation:

(i)

x³+y³=

Plugging in values

$2^3+8^3=\\2*2*2+8*8*8=\\4*2+64*8=\\8+512=\\520$

(ii)

$\sqrt[3]{y}$

Plugging in values

$\sqrt[3]{8} =\\2$

Since 2×2×2=8
