Which of the following expressions is the conjugate of a complex number with 3 as the real part and –2i as the imaginary part?
3 + 2i
3 – 2i
3i + 2
3i – 2

(A)

Step-by-step explanation:

It is given that there is a complex number with 3 as the real part and –2i as the imaginary part that is:

The number is=

Now, The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign.

Thus, the complex conjugate of is as number remains same with equal real and imaginary part in magnitude but opposite in sign.

Thus, option A is correct.

we know that

The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign

In this problem we have

so

the conjugate is equal to

-----> equal real part and imaginary part equal in magnitude but opposite in sign

the answer is the option

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant
