Simplify the expression -5+i/2i Can someone please explain this to me!
Aleks04 [339]
Think of it as -5+1i/2i, since 1i=i. From there, the i's could cancel out since dividing a number by itself would just equal 1. It would then be -5+1/2 which would be simplified to -4 1/2. No need to worry about those i's at all!
