Datrys [(x^-2)/(xy)^3]^1.5

$$[ \frac { ( x ^ { - 2 } ) } { ( x y ) ^ { 3 } } ] ^ { 1.5 }$$

Enrhifo

$$\frac{1}{\left(yx^{\frac{5}{3}}\right)^{4.5}}$$

Camau Ateb

Ehangu \left(xy\right)^{3}.

$$\left(\frac{x^{-2}}{x^{3}y^{3}}\right)^{1.5}$$

Er mwyn rhannu pwerau sy’n rhannu’r un sail, tynnwch esbonydd yr enwadur o esbonydd y rhifiadur.

$$\left(\frac{1}{y^{3}x^{5}}\right)^{1.5}$$

I godi \frac{1}{y^{3}x^{5}} i bŵer, codwch y rhifiadur a'r enwadur i bŵer ac yna rhannwch nhw.

$$\frac{1^{1.5}}{\left(y^{3}x^{5}\right)^{1.5}}$$

Cyfrifo 1 i bŵer 1.5 a chael 1.

$$\frac{1}{\left(y^{3}x^{5}\right)^{1.5}}$$

Ehangu \left(y^{3}x^{5}\right)^{1.5}.

$$\frac{1}{\left(y^{3}\right)^{1.5}\left(x^{5}\right)^{1.5}}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch 3 a 1.5 i gael 4.5.

$$\frac{1}{y^{4.5}\left(x^{5}\right)^{1.5}}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch 5 a 1.5 i gael 7.5.

$$\frac{1}{y^{4.5}x^{7.5}}$$

Gwahaniaethu w.r.t. x

$$-\frac{15y}{2\left(yx^{\frac{17}{11}}\right)^{5.5}}$$
