Final answer:
The conjugate of √3 - √17 is √3 + √17, which is typically used to rationalize denominators or simplify expressions in algebra. So, the correct answer is B.
Step-by-step explanation:
The question asks for the conjugate of a complex number, specifically √3 - √17. In mathematics, the conjugate of a complex number is obtained by changing the sign of the imaginary component. However, since √3 and √17 are both real numbers, in this context we're looking at a binomial with two square roots.
The conjugate of the expression √3 - √17 is √3 + √17.
This operation is used to rationalize denominators or simplify certain expressions in algebra.
algebra. So, the correct answer is B. √3 + √17.
