Answer:

The first answer which says $9x^{4} \sqrt{5}$

Step-by-step explanation:

In this question, we just simplify the equation in the following way...

$2x^{2} \sqrt{5x^{4} } +7\sqrt{5x^{8} } = 2x^{2} \sqrt{5} x^{2} + 7\sqrt{5} x^{4} = 2\sqrt{5} x^{4} + 7\sqrt{5} x^{4} = 9\sqrt{5} x^{4} = 9x^{4} \sqrt{5}$

Therefore the first answer it the right one.
