What is the conjugate of -8-4i?

The conjugate of -8-4i is -8+4i. It is obtained by changing the sign of the imaginary part of the complex number.


What is 2-4i over 4 plus 2i put in the form of a plus bi?

To solve this type of problem, multiply both the numerator and denominator by the conjugate of the denominator. (2 - 4i) / (4 + 2i) = (2 - 4i)(4 - 2i) / (4 + 2i)(4 - 2i) then expand all the terms, and simplify. = (8 - 20i + 8i2) / (16 - 4i2) = (8 - 20i - 8) / (16 + 4) = -20i / 20 = -i Which in the required answer format becomes, 0 + i.


What is the complex form of 4 plus 4i plus 4 plus 6i?

What is the answer to (-3 plus 4i)(8-2i)?

There is a mathematical symbol missing and I am assuming the question to be -2i(8i + 4) - 8(4 - 4i) which is -16i^2 - 8 - 32 - 32i which is -16(-1) - 8 - 32 - 32i which is +16 - 8 - 32 - 32i which is -24 -32i


What is the sum of (7 plus 3i) plus (8 plus 9i)?

(7 + 3i) + (8 + 9i) = (7 + 8) + (3i + 9i) = (7 + 8) + (3 + 9)i = 15 + 12i Which can also be written as: 15 + 12i = 3(5 + 4i).


How do you divide complex numbers?

When dividing complex numbers you must:Write the problem in fractional formRationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator.You must remember that a complex number times its conjugate will give a real number.a complex number 2+2i. the conjugate to this is 2-i1. Multiply both together gives a real number.(2+2i)(2-2i) = 4 -4i + 4i + (-4i2) (and as i2 = -1) = 8To divide a complex number by a real number simply divide the real parts by the divisor.(8+4i)/2 = (4+2i)To divide a real number by a complex number.1. make a fraction of the expression 8/(2+2i)2. multiply by 1. express 1 as a fraction of the divisor's conjunction. 8/(2+2i)*(2-2i)/(2-2i)3. multiply numerator by numerator and denominator by denominator.(16-16i)/84. and simplify 2-2i
