Success Criteria

  • Interface result: The target cell shows the square root result of the complex number.
  • Next action: You can continue copying the formula, editing the argument, or filling it down.

Tips While Using

3. Review results that update after data changes

Entry point: a worksheet cell that already contains IMSQRT

  1. First complete the IMSQRT formula in a cell.
  2. Change the referenced value in the formula, or replace the complex-number string.
  3. Press Enter to confirm the change.
  4. Check whether the result cell updates at the same time.

Success Criteria

  • Interface result: The result cell shows the updated calculation result.
  • Next action: You can continue linking other formulas or save the worksheet.

Tips While Using

  • Common mistake: If the referenced content is not in a valid complex-number format, the result may not return correctly.
