Solve (1)(-sqrt{5})^2-sqrt{(-3)^2}

$$( 1 ) ( - \sqrt { 5 } ) ^ { 2 } - \sqrt { ( - 3 ) ^ { 2 } }$$

Evaluate

$$2$$

Solution Steps

Calculate -\sqrt{5} to the power of 2 and get \left(\sqrt{5}\right)^{2}.

$$1\left(\sqrt{5}\right)^{2}-\sqrt{\left(-3\right)^{2}}$$

Calculate -3 to the power of 2 and get 9.

$$1\left(\sqrt{5}\right)^{2}-\sqrt{9}$$

Calculate the square root of 9 and get 3.

$$1\left(\sqrt{5}\right)^{2}-3$$

The square of \sqrt{5} is 5.

$$1\times 5-3$$

Multiply 1 and 5 to get 5.

$$5-3$$

Subtract 3 from 5 to get 2.

$$2$$

Factor

$$2$$
