Solve (-1^2-9)sqrt{3-1-(-1^2)+4}

$$(- { 1 }^{ 2 } -9) \sqrt{ 3-1-(- { 1 }^{ 2 } )+4 }$$

Evaluate

$$-10\sqrt{7}\approx -26.457513111$$

Solution Steps

Calculate 1 to the power of 2 and get 1.

$$\left(-1-9\right)\sqrt{3-1-\left(-1^{2}\right)+4}$$

Subtract 9 from -1 to get -10.

$$-10\sqrt{3-1-\left(-1^{2}\right)+4}$$

Subtract 1 from 3 to get 2.

$$-10\sqrt{2-\left(-1^{2}\right)+4}$$

Calculate 1 to the power of 2 and get 1.

$$-10\sqrt{2-\left(-1\right)+4}$$

The opposite of -1 is 1.

$$-10\sqrt{2+1+4}$$

Add 2 and 1 to get 3.

$$-10\sqrt{3+4}$$

Add 3 and 4 to get 7.

$$-10\sqrt{7}$$
