Full solution

Q. Write 8 \sqrt{-8} in simplest radical form.\newlineAnswer:
  1. Express as Product: Express 8\sqrt{-8} as the product of square roots and 1\sqrt{-1}.8=1×8=1×8\sqrt{-8} = \sqrt{-1 \times 8} = \sqrt{-1} \times \sqrt{8}
  2. Use Imaginary Unit: Express 1\sqrt{-1} as the imaginary unit ii and simplify 8\sqrt{8}.8=1×8=i×4×2=i×4×2\sqrt{-8} = \sqrt{-1} \times \sqrt{8} = i \times \sqrt{4 \times 2} = i \times \sqrt{4} \times \sqrt{2}
  3. Simplify Square Root: Simplify the square root of 44, which is a perfect square.8=i×4×2=i×2×2=2i×2\sqrt{-8} = i \times \sqrt{4} \times \sqrt{2} = i \times 2 \times \sqrt{2} = 2i \times \sqrt{2}
