Datrys v^frac{2{5}}*v^frac{2{3}}

$$v ^ { \frac { 2 } { 5 } } \cdot v ^ { \frac { 2 } { 3 } }$$

Gwahaniaethu w.r.t. v

$$\frac{16\sqrt[15]{v}}{15}$$

Camau gan ddefnyddio Rheol Deilliadol ar gyfer Cynnyrch

Ar gyfer unrhyw ddau ffwythiant y mae modd eu gwahaniaethu, deilliad cynnyrch dwy ffwythiant yw’r ffwythiant cyntaf wedi’i luosi â deilliad yr ail wedi’i ychwanegu at ffwythiant yr ail amser wedi’i luosi â’r deilliad cyntaf.

$$v^{\frac{2}{5}}\frac{\mathrm{d}}{\mathrm{d}v}(v^{\frac{2}{3}})+v^{\frac{2}{3}}\frac{\mathrm{d}}{\mathrm{d}v}(v^{\frac{2}{5}})$$

Deilliad polynomaial yw swm deilliadau ei dermau. Deilliad term cyson yw 0. Y deilliad o ax^{n} yw nax^{n-1}.

$$v^{\frac{2}{5}}\times \frac{2}{3}v^{\frac{2}{3}-1}+v^{\frac{2}{3}}\times \frac{2}{5}v^{\frac{2}{5}-1}$$

Symleiddio.

$$v^{\frac{2}{5}}\times \frac{2}{3}v^{-\frac{1}{3}}+v^{\frac{2}{3}}\times \frac{2}{5}v^{-\frac{3}{5}}$$

I luosi pwerau sy’n rhannu’r un sail, ychwanegwch eu hesbonyddion.

$$\frac{2}{3}v^{\frac{2}{5}-\frac{1}{3}}+\frac{2}{5}v^{\frac{2}{3}-\frac{3}{5}}$$

Symleiddio.

$$\frac{2}{3}\sqrt[15]{v}+\frac{2}{5}\sqrt[15]{v}$$

Enrhifo

$$v^{\frac{16}{15}}$$
