Final answer:
The conjugate of '6 + √(x+2)' is '6 - √(x+2)', altering only the sign between the terms.
Step-by-step explanation:
The conjugate of a complex number or expression changes the sign between two terms in the expression. For the expression '6 + √(x+2)' with the condition 'x ≥ -2', the conjugate is '6 - √(x+2)'. This is because we take the original expression and change the sign of the square root term while keeping the real number part the same.
