identify the conjugate of the radical below

Answer:
D) ( 5 + [tex]\sqrt{3^3}[/tex]
Step-by-step explanation:
Let's see the definition.
In mathematics conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y.
The given expression is (5 - [tex]\sqrt{3^3}[/tex])
To find the conjugate change the sign.
Therefore, the conjugate is (5 + [tex]\sqrt{3^3}[/tex].
Answer: D) 5 + [tex]\sqrt{3^3}[/tex]
Thank you.
