\( \int \frac { z ^ { 3 } } { ( 7 z ^ { 2 } + 3 ) ^ { 3 / 2 } } d z \)

Solve the correct word problem from the previous step. The answer is \( \square \). (Type a whole number.)

15. \( \left\{\begin{array}{l}y=-2 x+7 \\ -3 x+y=-8\end{array}\right. \)

11. \( \left\{\begin{array}{l}x=11+y \\ 2 x+y=19\end{array}\right. \)

Use properties of logarithms to expand the \[ \log \left[\frac{10 x^{5} \sqrt[3]{8-x}}{3(x+1)^{2}}\right] \] \( \log \left[\frac{10 x^{5} \sqrt[3]{8-x}}{3(x+1)^{2}}\right]=\square \)
