Datrys x=42y*y^3

$$x = 42 y * y ^ { 3 }$$

Datrys ar gyfer x

$$x=42y^{4}$$

Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 1 a 3 i gael 4.

$$x=42y^{4}$$

Datrys ar gyfer y (complex solution)

$$y=\frac{42^{\frac{3}{4}}i\sqrt[4]{x}}{42}$$

$$y=\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}i\sqrt[4]{x}}{42}$$

Datrys ar gyfer y

$$y=\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}\text{, }x\geq 0$$
