Express the radical using the imaginary unit, i. Express your answer in simplified form. +-sqrt(-4)=+-

Express as product of square roots: Express ±sqrt(-4) as the product of square roots and sqrt(-1). ±sqrt(-4) = ±sqrt(-1 * 4)Recognize imaginary unit: Recognize that sqrt(-1) is the imaginary unit i. ±sqrt(-4) = ±sqrt(-1) * sqrt(4)Simplify square root of 4: Simplify the square root of 4, which is 2. ±sqrt(-4) = ±i * 2Combine ± and 2 for final form: Combine the ± and the 2 to get the final simplified form. ±sqrt(-4) = ±2i

Q. Express the radical using the imaginary unit,

i

\newline

Express your answer in simplified form.

\newline

\pm \sqrt{-4}= \pm

Express as product of square roots: Express $\pm\sqrt{-4}$ as the product of square roots and $\sqrt{-1}$ . $\newline$ $\pm\sqrt{-4} = \pm\sqrt{-1 \cdot 4}$
Recognize imaginary unit: Recognize that $\sqrt{-1}$ is the imaginary unit $i$ . $\newline$ $\pm\sqrt{-4} = \pm\sqrt{-1} \cdot \sqrt{4}$
Simplify square root of $4$ : Simplify the square root of $4$ , which is $2$ . $\newline$ $\pm\sqrt{-4} = \pm i \times 2$
Combine $\pm$ and $2$ for final form: Combine the $\pm$ and the $2$ to get the final simplified form. $\newline$ $\pm\sqrt{-4} = \pm 2i$
