Verified step by step guidance1
Identify the complex number given in the problem: \( \frac{9 + \sqrt{-16}}{3} \).
Recognize that \( \sqrt{-16} \) can be expressed using the imaginary unit \( i \), where \( \sqrt{-16} = 4i \).
Substitute \( \sqrt{-16} \) with \( 4i \) in the expression: \( \frac{9 + 4i}{3} \).
Separate the real and imaginary parts of the complex number: \( \frac{9}{3} + \frac{4i}{3} \).
Simplify each part to write the complex number in standard form: \( 3 + \frac{4}{3}i \).
