Q. Express the radical using the imaginary unit, i.Express your answer in simplified form.±−24=±□
Express as product of square roots: Express ±−24 as the product of square roots and −1.±−24=±−1⋅24
Factor 24 into prime factors: Factor 24 into its prime factors to simplify the square root.24=23×3So, ±24=±23×3
Simplify square root of 24: Simplify the square root of 24 by taking out the square root of 4 (which is a perfect square and a factor of 24).±23×3=±22×2×3= ±2×2×3= ±2×6
Express −1 as i: Express ±−1 as the imaginary unit i.±−1=±i
Combine results: Combine the results from Step 3 and Step 4 to express the original expression as a complex number.±−24=±i⋅2⋅6=±2i⋅6
