Full solution

Q. Express the radical using the imaginary unit, i i .\newlineExpress your answer in simplified form.\newline±15=± \pm \sqrt{-15}= \pm
  1. Rewrite as Product: Express ±15\pm\sqrt{-15} as the product of square roots and 1\sqrt{-1}.\newline±15=±1×15\pm\sqrt{-15} = \pm\sqrt{-1 \times 15}
  2. Express as Complex Number: Express ±1×15\pm\sqrt{-1 \times 15} as a complex number by using ii for 1\sqrt{-1}.\newline±15=±1×15\pm\sqrt{-15} = \pm\sqrt{-1} \times \sqrt{15}\newline=±i×15= \pm i \times \sqrt{15}
  3. Combine for Simplification: Simplify the expression by combining the ±\pm sign with ii.±15=±i×15=±i15\pm\sqrt{-15} = \pm i \times \sqrt{15} = \pm i \sqrt{15}
