Answer:

The complex conjugate of #3+1i# is #3-1i#

Explanation:

The complex conjugate of a number is another number with a real component equal to the original number and an imaginary component equal in magnitude but with the opposite sign.

#color(red)("real")+color(blue)("imaginary")#

# color(red)(3)+color(blue)(1i)#

So the complex conjugate is
#color(red)(3) + color(blue)((-1i)) = color(red)(3)color(blue)(-1i)#
