Find the real and imaginary parts of the complex number.
4 - √-11
I know that the real part of this is 4, but I don't know the imaginary portion.
Wow, I'll bet OP is REALLY confused now!
You can't take the square root of a REAL number. Thank you potato salad!
From Mr. Fantastic's post:
The imaginary part is b. The i does not get included. The imaginary part is the coefficient of i.
The definition of an imaginary number is a number when squared gives a negative result. $\displaystyle i^2 = -1 $
"i" is a symbol with the property that $\displaystyle i^2 = -1$
The "real" part of the complex number $\displaystyle 4-i\sqrt{11}$ = the real number "4" AND the imaginary part of the complex number is the real number $\displaystyle \sqrt{11}$
How's that sound?
