Question

Find the additive inverse of -7+5i.

Answer 1

Required additive inverse is
`-7-5i`.

Explanation:

Given number is
`-7+5i`.

Now we need to find about what is that additive inverse of the given number
`-7+5i`.

We know that if complex number is
`a+bi` then it's additive inverse is given by
`a-bi`.

Basically we need to change the sign of imaginary term.

imaginary term in given number
`-7+5i` is +5i.

Changing sign of +5i gives -5i.

Hence required additive inverse is
`-7-5i`.
