what's the simplified version?

Answer:
D) [tex]x^{12}[/tex]
Step-by-step explanation:
Note that all the base are the same (the variable x). You are multiplying the three like terms together. Simply add the powers together:
[tex]x^{3} * x^{4} * x^{5} = x^{3 + 4 + 5} = x^{12}[/tex]
D) [tex]x^{12}[/tex] is your answer.
