Solve sqrt[3]{-64}*0.2^3-4/10

$$\sqrt[ 3 ] { - 64 } \times 0.2 ^ { 3 } - \frac { 4 } { 10 }$$

Evaluate

$$-0.432$$

Solution Steps

Calculate \sqrt[3]{-64} and get -4.

$$-4\times 0.2^{3}-\frac{4}{10}$$

Calculate 0.2 to the power of 3 and get 0.008.

$$-4\times 0.008-\frac{4}{10}$$

Multiply -4 and 0.008 to get -0.032.

$$-0.032-\frac{4}{10}$$

Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.

$$-0.032-\frac{2}{5}$$

Subtract \frac{2}{5} from -0.032 to get -\frac{54}{125}.

$$-\frac{54}{125}$$

Factor

$$-0.432$$
