Explanation:

The one that you highlighted is correct. The rest of the problems equal

$16x {}^(10)$

While the third equation equal

$2 {x}^(7) + 14 {x}^(7) = 16 {x}^(7)$

I would bring the x value to the 7th power instead of the 4th using the power of product rule.

So I would make the equation look like

$x {}^(7) ( {2x}^(3) + {14x}^(3) )$ which equal

16x^10
