Q. Express the radical using the imaginary unit, i.Express your answer in simplified form.±−100=±□
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 ±−100 by factoring out the negative as the square root of −1 times the square root of 100.
Factoring out the negative: Next, we know that −1 is equal to i, and 100 is equal to 10. So we can express ±−100 as ±i×100.
Simplifying the expression: Now, we simplify the expression by multiplying i with the square root of 100, which is 10. This gives us ±i×10, which can be written as ±10i.
Final simplified complex number form: Finally, we have the expression in its simplest form, which is ±10i. This is the simplified complex number form of the original expression ±−100.
