Answer:

A.
x^5

Explanation:

We are asked to find the greatest common factor of
19x^7 and
3x^5.

Factors of
19x^7:
19\cdot x^5* x^2

Factors of
3x^5:
3\cdot x^5

We can see that both terms share a common factor that is
x^5, therefore, the greatest common factor of both terms is
x^5.

The answer is A. x^5

To get the GCF of the two values, it is best to get the invidivual GCFs from the numbers and variables.

19 and 3 do not have a GCF. So, the next GCF to get is between x^7 and x^5. The GCF for both is x^ 5.

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.
