Answer: To find the complex conjugate of 4+7i we change the sign of the imaginary part. Thus the complex conjugate of 4+7i is 4 − 7i.
Likewise, people ask, what is 7i?
Where I is √-1 (complex no) 7i means √-7. This is because the value of i or iota as it is called in Greek has the value of √-1. Therefore, √-7 = √(-1)*7 which is equivalent to 7i.
Also Know, what is the conjugate of 4i? Complex Conjugate Formula. The complex conjugate of a complex number is defined as two complex number having an equal real part and imaginary part equal in magnitude but opposite in sign. For example, the complex conjugate of 3 + 4i is 3 - 4i, where the real part is 3 for both and imaginary part varies in sign.
Then, what is the conjugate of 2i?
As a general rule, the complex conjugate of a+bi is a−bi . While 2i may not seem to be in the a+bi form, it can be written as 0+2i .
What is the conjugate of 5i?
Explanation: For any complex number in rectangular form x+iy, the complex conjugate is x-iy.
