Questions & Step-by-Step Solutions

What is the value of (2 + 3i) + (4 - 2i)?
  • Step 1: Identify the real parts of the complex numbers. The real part of (2 + 3i) is 2, and the real part of (4 - 2i) is 4.
  • Step 2: Add the real parts together. So, 2 + 4 = 6.
  • Step 3: Identify the imaginary parts of the complex numbers. The imaginary part of (2 + 3i) is 3i, and the imaginary part of (4 - 2i) is -2i.
  • Step 4: Add the imaginary parts together. So, 3i + (-2i) = 3i - 2i = 1i.
  • Step 5: Combine the results from Step 2 and Step 4. This gives us 6 + 1i.
  • Step 6: Write the final answer in standard form. The final answer is 6 + i.
