Datrys 2x^frac{3{5}}*9x^2

$$2 x ^ { \frac { 3 } { 5 } } \cdot 9 x ^ { 2 }$$

Enrhifo

$$18x^{\frac{13}{5}}$$

Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch \frac{3}{5} a 2 i gael \frac{13}{5}.

$$2x^{\frac{13}{5}}\times 9$$

Lluosi 2 a 9 i gael 18.

$$18x^{\frac{13}{5}}$$

Gwahaniaethu w.r.t. x

$$\frac{234x^{\frac{8}{5}}}{5}$$

Camau gan Ddefnyddio Diffiniad o Ddeilliad

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch \frac{3}{5} a 2 i gael \frac{13}{5}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(2x^{\frac{13}{5}}\times 9)$$

Lluosi 2 a 9 i gael 18.

$$\frac{\mathrm{d}}{\mathrm{d}x}(18x^{\frac{13}{5}})$$

Deilliad ax^{n} yw nax^{n-1}.

$$\frac{13}{5}\times 18x^{\frac{13}{5}-1}$$

Lluoswch \frac{13}{5} â 18.

$$\frac{234}{5}x^{\frac{13}{5}-1}$$

Tynnu 1 o \frac{13}{5}.

$$\frac{234}{5}x^{\frac{8}{5}}$$
