Solve sqrt{left(-1-2right)^2+left(-1-0right)^2}

$$\sqrt{ { \left(-1-2 \right) }^{ 2 } + { \left(-1-0 \right) }^{ 2 } }$$

Evaluate

$$\sqrt{10}\approx 3.16227766$$

Solution Steps

Subtract 2 from -1 to get -3.

$$\sqrt{\left(-3\right)^{2}+\left(-1-0\right)^{2}}$$

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

$$\sqrt{9+\left(-1-0\right)^{2}}$$

Subtract 0 from -1 to get -1.

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

Calculate -1 to the power of 2 and get 1.

$$\sqrt{9+1}$$

Add 9 and 1 to get 10.

$$\sqrt{10}$$
