$$\frac{24x\left(x^{3}+1\right)^{\frac{3}{2}}-3x^{4}\times 72\left(x^{3}+1\right)^{\frac{1}{2}}}{15\left(x^{3}+1\right)^{\frac{3}{2}}}$$

Korrutage 3 ja 72, et leida 216.

$$\frac{24x\left(x^{3}+1\right)^{\frac{3}{2}}-216x^{4}\left(x^{3}+1\right)^{\frac{1}{2}}}{15\left(x^{3}+1\right)^{\frac{3}{2}}}$$
