Solve sqrt{0.04}+sqrt[3]{-8}-sqrt{1/4}

$$\sqrt { 0.04 } + \sqrt[ 3 ] { - 8 } - \sqrt { \frac { 1 } { 4 } }$$

Evaluate

$$-2.3$$

Solution Steps

Calculate the square root of 0.04 and get 0.2.

$$0.2+\sqrt[3]{-8}-\sqrt{\frac{1}{4}}$$

Calculate \sqrt[3]{-8} and get -2.

$$0.2-2-\sqrt{\frac{1}{4}}$$

Subtract 2 from 0.2 to get -1.8.

$$-1.8-\sqrt{\frac{1}{4}}$$

Rewrite the square root of the division \frac{1}{4} as the division of square roots \frac{\sqrt{1}}{\sqrt{4}}. Take the square root of both numerator and denominator.

$$-1.8-\frac{1}{2}$$

Subtract \frac{1}{2} from -1.8 to get -\frac{23}{10}.

$$-\frac{23}{10}$$

Factor

$$-2.3$$
