Antwort

The answer is -2 - 7i

Erklärung

  1. Identify the given complex number.
    The given complex number is -2 + 7i. This is in the standard form a + bi, where a = -2 and b = 7.

  2. Define the conjugate of a complex number.
    The conjugate of a complex number a + bi is given by a - bi. This involves changing the sign of the imaginary part.

  3. Determine the conjugate.
    Applying the definition of the conjugate to the given complex number (-2 + 7i), we change the sign of the imaginary part (7i) to obtain -7i. Therefore, the conjugate is -2 - 7i.
