Passos de solució

Calculeu \frac{4}{9} elevat a -2 per obtenir \frac{81}{16}.

$$\frac{81}{16}+\sqrt[3]{-27}+\left(\frac{1}{5}\right)^{2}+\sqrt[3]{-\frac{8}{27}}+\left(\frac{3}{5}\right)^{0}$$

Calcula \sqrt[3]{-27} i obté -3.

$$\frac{81}{16}-3+\left(\frac{1}{5}\right)^{2}+\sqrt[3]{-\frac{8}{27}}+\left(\frac{3}{5}\right)^{0}$$

Resteu \frac{81}{16} de 3 per obtenir \frac{33}{16}.

$$\frac{33}{16}+\left(\frac{1}{5}\right)^{2}+\sqrt[3]{-\frac{8}{27}}+\left(\frac{3}{5}\right)^{0}$$

Calculeu \frac{1}{5} elevat a 2 per obtenir \frac{1}{25}.

$$\frac{33}{16}+\frac{1}{25}+\sqrt[3]{-\frac{8}{27}}+\left(\frac{3}{5}\right)^{0}$$

Sumeu \frac{33}{16} més \frac{1}{25} per obtenir \frac{841}{400}.

$$\frac{841}{400}+\sqrt[3]{-\frac{8}{27}}+\left(\frac{3}{5}\right)^{0}$$

Calcula \sqrt[3]{-\frac{8}{27}} i obté -\frac{2}{3}.

$$\frac{841}{400}-\frac{2}{3}+\left(\frac{3}{5}\right)^{0}$$

Resteu \frac{841}{400} de \frac{2}{3} per obtenir \frac{1723}{1200}.

$$\frac{1723}{1200}+\left(\frac{3}{5}\right)^{0}$$

Calculeu \frac{3}{5} elevat a 0 per obtenir 1.

$$\frac{1723}{1200}+1$$

Sumeu \frac{1723}{1200} més 1 per obtenir \frac{2923}{1200}.

$$\frac{2923}{1200}$$

Factoritzar

$$\frac{37 \cdot 79}{2 ^ {4} \cdot 3 \cdot 5 ^ {2}} = 2\frac{523}{1200} = 2,4358333333333335$$
