Questions & Step-by-Step Solutions

Which of the following is the conjugate of the complex number 2 - 3i? (2020)
  • Step 1: Identify the complex number given in the question, which is 2 - 3i.
  • Step 2: Understand that a complex number is in the form a + bi, where 'a' is the real part and 'b' is the imaginary part.
  • Step 3: In the complex number 2 - 3i, the real part (a) is 2 and the imaginary part (b) is -3.
  • Step 4: The conjugate of a complex number a + bi is found by changing the sign of the imaginary part. So, it becomes a - bi.
  • Step 5: Apply this rule to the complex number 2 - 3i. The conjugate will be 2 + 3i.
