Today’s homework is HW 4.10 – Simplifying Square Roots of Negatives, and in particular how imaginary numbers are used to accomplish this goal. You can find the notes here and see some more examples in this video. **PLEASE REMEMBER**: negative radicands do not multiply. Pull out the *i* first, before you multiply.
