Resolver frac{24x(x^{3}+1)^{3/2}-3x^{2}(72x^{2}(x^3+1)^frac{1{2}})}{15(x^3+1)^3/2}

$$\frac { 24 x ( x ^ { 3 } + 1 ) ^ { 3 / 2 } - 3 x ^ { 2 } ( 72 x ^ { 2 } ( x ^ { 3 } + 1 ) ^ { \frac { 1 } { 2 } } ) } { 15 ( x ^ { 3 } + 1 ) ^ { 3 / 2 } }$$

Calcular

$$-\frac{8x\left(8x^{3}-1\right)}{5\left(x^{3}+1\right)}$$

Pasos de solución curta

Para multiplicar potencias da mesma base, suma os seus expoñentes. Suma 2 e 2 para obter 4.

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

Multiplica 3 e 72 para obter 216.

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

Factoriza as expresións que aínda non o están.

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

Anula 3\sqrt{x^{3}+1} no numerador e no denominador.

$$\frac{8x\left(2x-1\right)\left(-4x^{2}-2x-1\right)}{5\left(x^{3}+1\right)}$$

Expande a expresión.

$$\frac{-64x^{4}+8x}{5x^{3}+5}$$

Factorizar

$$-\frac{8x\left(2x-1\right)\left(4x^{2}+2x+1\right)}{5\left(x+1\right)\left(x^{2}-x+1\right)}$$
