Solve =1sqrt{sqrt{1}-4}

$$= 1 \sqrt { \sqrt { 1 } - 4 }$$

Evaluate (complex solution)

$$\sqrt{3}i\approx 1.732050808i$$

Solution Steps

Calculate the square root of 1 and get 1.

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

Subtract 4 from 1 to get -3.

$$1\sqrt{-3}$$

Factor -3=3\left(-1\right). Rewrite the square root of the product \sqrt{3\left(-1\right)} as the product of square roots \sqrt{3}\sqrt{-1}. By definition, the square root of -1 is i.

$$1\sqrt{3}i$$

Multiply 1 and i to get i.

$$i\sqrt{3}$$

Evaluate

$$\text{Indeterminate}$$

Solution Steps

Calculate the square root of 1 and get 1.

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

Subtract 4 from 1 to get -3.

$$1\sqrt{-3}$$

For any term t, t\times 1=t and 1t=t.

$$\sqrt{-3}$$

Real Part (complex solution)
