The modulus of the square root of the conjugate of \(-7+24 \sqrt{-1}\) is ....
- A \(3\)
- B \(4\)
- C \(16\)
- D \(5\)
Answer & Solution
Correct Answer
(D) \(5\)
Step-by-step Solution
Detailed explanation
\(z = -7 + 24i\) \(|\bar{z}| = |-7 - 24i| = \sqrt{(-7)^2 + (-24)^2} = \sqrt{49 + 576} = \sqrt{625} = 25\)
