Question

Which of the following is a conjugate for 7 + i Square root of 2? (2 points) − 7 + i Square root of 2 7 − i Square root of 2 i Square root of 2 + 7 −i Square root of 2 − 7

Answer 1

`7-√(2)i`

Explanation:

Given number is
`7+√(2)i`. We need to find the complex conjugate of the given number.

We will use the general rule to find out the complex conjugate of the number.

The complex conjugate of
`a+bi` will be
`a-bi`

And the complex conjugate of
`7+√(2)i\ became\ 7-√(2)i`

So, the complex conjugate of
`7+√(2)i` is
`7-√(2)i`
