Réitigh -18/11*-90/3x

$$- 18 / 11 \cdot - 90 / 3 x$$

Luacháil

$$\frac{540x}{11}$$

Céimeanna Réitigh

Roinn 90 faoi 3 chun 30 a fháil.

$$-\frac{18}{11}\left(-30\right)x$$

Scríobh -\frac{18}{11}\left(-30\right) mar chodán aonair.

$$\frac{-18\left(-30\right)}{11}x$$

Méadaigh -18 agus -30 chun 540 a fháil.

$$\frac{540}{11}x$$

Difreálaigh w.r.t. x

$$\frac{540}{11} = 49\frac{1}{11} = 49.09090909090909$$

Céimeanna ag Baint Úsáid as Sainiú Díorthaigh

Roinn 90 faoi 3 chun 30 a fháil.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-\frac{18}{11}\left(-30\right)x)$$

Scríobh -\frac{18}{11}\left(-30\right) mar chodán aonair.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{-18\left(-30\right)}{11}x)$$

Méadaigh -18 agus -30 chun 540 a fháil.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{540}{11}x)$$

Is é díorthach ax^{n} ná nax^{n-1}.

$$\frac{540}{11}x^{1-1}$$

Dealaigh 1 ó 1.

$$\frac{540}{11}x^{0}$$

Do théarma ar bith t ach amháin 0, t^{0}=1.

$$\frac{540}{11}\times 1$$

Do théarma ar bith t, t\times 1=t agus 1t=t.
