Answer:
x^3 + 3 (the third option)
Step-by-step explanation:
In this question, we are asked to find the missing value inside the parenthesis.
x^8 +3x^5 = x^5(____)
We see that x^5 is factored out of the original expression, so we can obtain the answer by dividing both terms by x^5.
x^8 / x^5 = x^3
3x^5/ x^5 = 3
So we have: x^3 + 3.
