Full solution

Q. Express the radical using the imaginary unit, i i .\newlineExpress your answer in simplified form.\newline±80=± \pm \sqrt{-80}= \pm
  1. Expressing 80\sqrt{-80} as a product: Express ±80\pm\sqrt{-80} as the product of square roots and 1\sqrt{-1}.
    ±80=±1×80\pm\sqrt{-80} = \pm\sqrt{-1 \times 80}
  2. Factoring 8080 into 16×516 \times 5: Factor 8080 into 16×516 \times 5, since 1616 is a perfect square.\newline±80=±1×16×5\pm\sqrt{-80} = \pm\sqrt{-1 \times 16 \times 5}
  3. Expressing 1\sqrt{-1} as ±i\pm i: Express ±1\pm\sqrt{-1} as ±i\pm i and take the square root of 1616.
    ±80=±1165\pm\sqrt{-80} = \pm\sqrt{-1} \cdot \sqrt{16} \cdot \sqrt{5}
    = ±i45\pm i \cdot 4 \cdot \sqrt{5}
  4. Simplifying the expression: Simplify the expression by multiplying the real numbers. ±80=±4i5\pm\sqrt{-80} = \pm 4i \cdot \sqrt{5}
