Q. Express the radical using the imaginary unit, i.Express your answer in simplified form.±−36=±
Recognizing the imaginary unit: First, we recognize that the square root of a negative number involves the imaginary unit i, where i2=−1. We can rewrite the expression ±−36 by factoring out the negative under the radical as the product of −1 and 36.
Simplifying the square root of 36: Next, we simplify the square root of 36, which is a perfect square. The square root of 36 is 6.
Expressing −1 as i: Now, we can express −1 as the imaginary unit i. Therefore, ±−36 becomes ±i×6.
Combining the ± sign with 6i: Finally, we combine the ± sign with 6i to get the simplified form of the expression, which is ±6i.
