Do I have this question right?

Answer 1

no

Answer 2

Okay I must have done something wrong

Answer 3

have you gotten to derivatives yet?

Answer 4

yes

Answer 5

then you should recognize this as the derivative of
\[f(x)=\sqrt[3]{x}\] at \(x=8\)
in other words, if
\[f(x)=\sqrt[3]{x}\] then
\[f'(8)=\lim_{h\to 0}\frac{\sqrt[3]{8+h}-\sqrt[3]{8}}{h}\]
