Passos Para a Resolução

Subtraia 1 de 4 para obter 3.

$$38+3\times 5^{-2}\times 2\times 4$$

Calcule 5 elevado a -2 e obtenha \frac{1}{25}.

$$38+3\times \frac{1}{25}\times 2\times 4$$

Multiplique 3 e \frac{1}{25} para obter \frac{3}{25}.

$$38+\frac{3}{25}\times 2\times 4$$

Multiplique \frac{3}{25} e 2 para obter \frac{6}{25}.

$$38+\frac{6}{25}\times 4$$

Multiplique \frac{6}{25} e 4 para obter \frac{24}{25}.

$$38+\frac{24}{25}$$

Some 38 e \frac{24}{25} para obter \frac{974}{25}.

$$\frac{974}{25}$$

Fatorizar

$$\frac{2 \cdot 487}{5 ^ {2}} = 38\frac{24}{25} = 38,96$$
