Answer:
The correct answer is D.
Step-by-step explanation:
In order to find this, we need to start by multiplying the two numbers under the square root symbol.
[tex]\sqrt[7]{x^{5}} * \sqrt[7]{x^{5}} = \sqrt[7]{x^{10}}[/tex]
Now we can simplify further. Since we're looking for the 7th root, we can pull out a factor of 7 as an x, leaving behind x^3.
[tex]x\sqrt[7]{x^{3} }[/tex]
