Could someone help me out with this question..? Which of the following is the conjugate of a complex number with −4 as the real part and 2 as the imaginary part? 2i − 4 2i + 4 −4 − 2i −4 + 2i
the real part stays the same and the imaginary part changes sign
i get feelings all the time but in math definitions and logic must corroborate the feelings
you have to change the sign on the imaginary term to get the conjugate.
now she hears me...
not b, c. -4 is the real part. the sign on the imaginary part changes sign. so -4 + 2 i is the original and -4 - 2i is the conjugate.
you got it girl
