Hi I'm really tight on time, so if someone could please answer this asap that would mean a lot. Thank you!
When 7-i is converted to the exponential form $re^{i \theta}$ , what is r?
Note: When converting a nonzero complex number to exponential form, the magnitude r should be positive, and the argument theta should satisfy 0 less than or equal to theta < 2pi.
Sorry for the bad format.
