Respuesta :

5 + 8i

given a complex number a ± bi then the complex conjugate is a ∓ bi

note the real part remains unchanged while the sign of the imaginary part reverses.

The conjugate of 5 - 8i is 5 + 8i

The conjugate of a complex number is the number that has the same real part but the opposite of its imaginary part

The given complex number is:

5  -  8i

The conjugate of a complex number of the form x + iy is given as:

x  - iy

Comparing 5 - 8i   with  x  +  iy:

x  =  5,   y  = -8

Applying similar rule for finding the conjugate of x + iy to 5 - 8i:

The conjugate of 5 - 8i is 5 + 8i
