Calcular

$$-\frac{2349}{4}=-587.25$$

Pasos da solución

O contrario de -4 é 4.

$$\left(17+4\right)\times 3-\left(25+\frac{1}{2}\right)^{2}$$

Suma 17 e 4 para obter 21.

$$21\times 3-\left(25+\frac{1}{2}\right)^{2}$$

Multiplica 21 e 3 para obter 63.

$$63-\left(25+\frac{1}{2}\right)^{2}$$

Suma 25 e \frac{1}{2} para obter \frac{51}{2}.

$$63-\left(\frac{51}{2}\right)^{2}$$

Calcula \frac{51}{2} á potencia de 2 e obtén \frac{2601}{4}.

$$63-\frac{2601}{4}$$

Resta \frac{2601}{4} de 63 para obter -\frac{2349}{4}.

$$-\frac{2349}{4}$$

Factorizar

$$-\frac{2349}{4} = -587\frac{1}{4} = -587.25$$
