Passos Para a Resolução

Multiplique 1 e 5 para obter 5.

$$\frac{\left(2-\frac{5+3}{5}\right)^{2}+\frac{5}{8}-\frac{3}{4}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Some 5 e 3 para obter 8.

$$\frac{\left(2-\frac{8}{5}\right)^{2}+\frac{5}{8}-\frac{3}{4}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Subtraia \frac{8}{5} de 2 para obter \frac{2}{5}.

$$\frac{\left(\frac{2}{5}\right)^{2}+\frac{5}{8}-\frac{3}{4}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Calcule \frac{2}{5} elevado a 2 e obtenha \frac{4}{25}.

$$\frac{\frac{4}{25}+\frac{5}{8}-\frac{3}{4}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Some \frac{4}{25} e \frac{5}{8} para obter \frac{157}{200}.

$$\frac{\frac{157}{200}-\frac{3}{4}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Subtraia \frac{3}{4} de \frac{157}{200} para obter \frac{7}{200}.

$$\frac{\frac{7}{200}-\left(\frac{6}{5}\times \frac{1}{3}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Multiplique \frac{6}{5} e \frac{1}{3} para obter \frac{2}{5}.

$$\frac{\frac{7}{200}-\left(\frac{2}{5}\right)^{4}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Calcule \frac{2}{5} elevado a 4 e obtenha \frac{16}{625}.

$$\frac{\frac{7}{200}-\frac{16}{625}\times \left(\frac{7\times 2+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Multiplique 7 e 2 para obter 14.

$$\frac{\frac{7}{200}-\frac{16}{625}\times \left(\frac{14+1}{2}\right)^{3}}{5-\frac{6}{5}}$$

Some 14 e 1 para obter 15.

$$\frac{\frac{7}{200}-\frac{16}{625}\times \left(\frac{15}{2}\right)^{3}}{5-\frac{6}{5}}$$

Calcule \frac{15}{2} elevado a 3 e obtenha \frac{3375}{8}.

$$\frac{\frac{7}{200}-\frac{16}{625}\times \frac{3375}{8}}{5-\frac{6}{5}}$$

Multiplique \frac{16}{625} e \frac{3375}{8} para obter \frac{54}{5}.

$$\frac{\frac{7}{200}-\frac{54}{5}}{5-\frac{6}{5}}$$

Subtraia \frac{54}{5} de \frac{7}{200} para obter -\frac{2153}{200}.

$$\frac{-\frac{2153}{200}}{5-\frac{6}{5}}$$

Subtraia \frac{6}{5} de 5 para obter \frac{19}{5}.

$$\frac{-\frac{2153}{200}}{\frac{19}{5}}$$

Divida -\frac{2153}{200} por \frac{19}{5} ao multiplicar -\frac{2153}{200} pelo recíproco de \frac{19}{5}.

$$-\frac{2153}{200}\times \frac{5}{19}$$

Multiplique -\frac{2153}{200} e \frac{5}{19} para obter -\frac{2153}{760}.

$$-\frac{2153}{760}$$

Fatorizar

$$-\frac{2153}{760} = -2\frac{633}{760} = -2,832894736842105$$
