Question

How can a conjugate be created from a complex number?

Answer 1

example: 7i is the congugate of -7i however -7 is NOT a congugate of 7. it works only for complex num

Answer 2

The complex conjugate of a + bi is a – bi, and similarly the complex conjugate of a – bi is a + bi. This consists of changing the sign of the imaginary part of a complex number. The real part is left unchanged.

Complex conjugates are indicated using a horizontal line over the number or variable. For example, .

Note: Complex conjugates are similar to, but not the same as, conjugates.

Answer 3

could i get a medal and fan:)pls

Answer 4

asing for medal is against COC

Answer 5

o well:)

Answer 6

it is not that -7i is a conjugate for 7i.
Conjugate is for complex numbers (a combination of an imaginary number and a real number.)

For example, a conjugate for \(\large\color{black}{ 3i+5 }\) is \(\large\color{blue}{ 3i-5 }\) (well, if you re-write \(\large\color{black}{ 3i+5 }\) as \(\large\color{black}{ 5+3i }\), you can also make it, \(\large\color{blue}{ 5-3i }\).

But for any: \(\large\color{black}{ ai+b }\) the conjugate is \(\large\color{blue}{ ai+b }\).
if you have more questions about it's purpose, ask and I'll give an example.
