Question

The conjugate of (5-√7) is what?

Answer 1

the conjugate of (5 - √7) is (5 + √7).

Explanation:

The conjugate of a complex number (or an expression with a square root of a non-perfect square) is obtained by changing the sign of the imaginary part or the term involving the square root. In this case, the given expression is (5 - √7). To find its conjugate, we change the sign of the term with the square root:

(5 + √7)

So, the conjugate of (5 - √7) is (5 + √7).

Answer 2

The conjugate of (5-√7) is (5+√7).
