Solve 28*5.7+1/2*10*5.7*5.7=

$$28 \times 5.7+ \frac{ 1 }{ 2 } \times 10 \times 5.7 \times 5.7=$$

Evaluate

$$322.05$$

Solution Steps

Multiply 28 and 5.7 to get 159.6.

$$159.6+\frac{1}{2}\times 10\times 5.7\times 5.7$$

Multiply \frac{1}{2} and 10 to get \frac{10}{2}.

$$159.6+\frac{10}{2}\times 5.7\times 5.7$$

Divide 10 by 2 to get 5.

$$159.6+5\times 5.7\times 5.7$$

Multiply 5 and 5.7 to get 28.5.

$$159.6+28.5\times 5.7$$

Multiply 28.5 and 5.7 to get 162.45.

$$159.6+162.45$$

Add 159.6 and 162.45 to get 322.05.

$$322.05$$

Factor

$$\frac{3 \cdot 19 \cdot 113}{5 \cdot 2 ^ {2}} = 322\frac{1}{20} = 322.05$$
