Q. Express the radical using the imaginary unit, i.Express your answer in simplified form.±−30=±
Recognize the involvement of imaginary unit i: Recognize that the square root of a negative number involves the imaginary unit i, where i2=−1. ±−30 can be expressed as ±−1⋅30.
Separate the square root of the product: Separate the square root of the product into the product of square roots. ±−1×30=±−1×30.
Replace −1 with i: Replace −1 with i to express the square root of −1 as an imaginary number.±−1×30=±i×30.
No further simplification of 30: Since there is no further simplification of 30, the expression is already in its simplest form.So, the final expression is ±i⋅30.
