Transcript text: Express $\sqrt{-841}$ in standard form of a complex number.
Solution
Solution Steps
To express \(\sqrt{-841}\) in the standard form of a complex number, we need to recognize that the square root of a negative number involves the imaginary unit \(i\), where \(i = \sqrt{-1}\). We can then separate the negative part and the positive part, and compute the square root of the positive part.
Step 1: Identify the Expression
We start with the expression \(\sqrt{-841}\). Since the square root of a negative number involves the imaginary unit \(i\), we can rewrite the expression as:
\[
\sqrt{-841} = \sqrt{841} \cdot \sqrt{-1} = \sqrt{841} \cdot i
\]
Step 2: Calculate the Square Root of the Positive Part
Next, we calculate \(\sqrt{841}\):
\[
\sqrt{841} = 29
\]
Step 3: Combine the Results
Now, we can combine the results to express \(\sqrt{-841}\) in standard form:
\[
\sqrt{-841} = 29i
\]
Final Answer
Thus, the square root of \(-841\) in standard form is \(\boxed{29i}\).
