Question

Which of the following is the conjugate of a complex number with 4 as the real part and -3 as the imaginary part?

-3+4i
3-4i
4+3i
4-3ii

Answer 1

i stands for imaginary, so the imaginary part of the number will always have i in it

so now you know you have -3i

your real number is just 4

the original expression is 4-3i

for a conjugate, you just switch the sign, so the conjugate of 4-3i is 4+3i

Answer 2
