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

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

Enrhifo

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

Camau Ateb Byr

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 2 a 2 i gael 4.

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

Lluosi 3 a 72 i gael 216.

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