$$\sqrt[ 3 ] { - 8 } - 2 \sqrt { 4 } + \sqrt { ( - 5 ) ^ { 2 } } =$$

Evaluate

$$-1$$

Solution Steps

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

$$-2-2\sqrt{4}+\sqrt{\left(-5\right)^{2}}$$

Calculate the square root of 4 and get 2.

$$-2-2\times 2+\sqrt{\left(-5\right)^{2}}$$

Multiply -2 and 2 to get -4.

$$-2-4+\sqrt{\left(-5\right)^{2}}$$

Subtract 4 from -2 to get -6.

$$-6+\sqrt{\left(-5\right)^{2}}$$

Calculate -5 to the power of 2 and get 25.

$$-6+\sqrt{25}$$

Calculate the square root of 25 and get 5.

$$-6+5$$

Add -6 and 5 to get -1.

$$-1$$

Factor
