Question 776084
Sure, it is a complex number, but why are you specifically calling it complex?  Did you mean something different than you wrote?


You ask about {{{3-sqrt(25)}}}.  As written, the coefficient on i is zero.  You have written a REAL number.  


{{{3-sqrt(5)=3-5=2}}}  OR  {{{3-sqrt(5)=3-(-5)=8}}}


DID YOU MEAN, {{{3-sqrt(-25)}}} or something else?
