Datrys (1/5)^-2*(2/3)^3+3^-2*3^5

$$( 1 / 5 ) ^ { - 2 } \cdot ( 2 / 3 ) ^ { 3 } + 3 ^ { - 2 } \cdot 3 ^ { 5 }$$

Enrhifo

$$\frac{929}{27}\approx 34.407407407$$

Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch -2 a 5 i gael 3.

$$\left(\frac{1}{5}\right)^{-2}\times \left(\frac{2}{3}\right)^{3}+3^{3}$$

Cyfrifo \frac{1}{5} i bŵer -2 a chael 25.

$$25\times \left(\frac{2}{3}\right)^{3}+3^{3}$$

Cyfrifo \frac{2}{3} i bŵer 3 a chael \frac{8}{27}.

$$25\times \frac{8}{27}+3^{3}$$

Lluosi 25 a \frac{8}{27} i gael \frac{200}{27}.

$$\frac{200}{27}+3^{3}$$

Cyfrifo 3 i bŵer 3 a chael 27.

$$\frac{200}{27}+27$$

Adio \frac{200}{27} a 27 i gael \frac{929}{27}.

$$\frac{929}{27}$$

Ffactor

$$\frac{929}{3 ^ {3}} = 34\frac{11}{27} = 34.407407407407405$$
