Passos Para a Resolução

Multiplique 10^{3} e 10^{-3} para obter 1.

$$98\times 120-10^{3}\times 98\times 200\times 10^{-3}-920\times 98\times 120\times 10^{-3}$$

Multiplique 10^{3} e 10^{-3} para obter 1.

$$98\times 120-98\times 200-920\times 98\times 120\times 10^{-3}$$

Multiplique 98 e 120 para obter 11760.

$$11760-98\times 200-920\times 98\times 120\times 10^{-3}$$

Multiplique 98 e 200 para obter 19600.

$$11760-19600-920\times 98\times 120\times 10^{-3}$$

Subtraia 19600 de 11760 para obter -7840.

$$-7840-920\times 98\times 120\times 10^{-3}$$

Multiplique 920 e 98 para obter 90160.

$$-7840-90160\times 120\times 10^{-3}$$

Multiplique 90160 e 120 para obter 10819200.

$$-7840-10819200\times 10^{-3}$$

Calcule 10 elevado a -3 e obtenha \frac{1}{1000}.

$$-7840-10819200\times \frac{1}{1000}$$

Multiplique 10819200 e \frac{1}{1000} para obter \frac{54096}{5}.

$$-7840-\frac{54096}{5}$$

Subtraia \frac{54096}{5} de -7840 para obter -\frac{93296}{5}.

$$-\frac{93296}{5}$$

Fatorizar

$$-\frac{93296}{5} = -18659\frac{1}{5} = -18659,2$$
