Your answer would be D)
[tex] \frac{ {x}^{6} \sqrt{z} }{ {y}^{3} } [/tex]
[tex] {x}^{6} [/tex] would remain as that, which is has in option D.
[tex] {y}^{ - 3} [/tex] would be 1/y³, as when you put a value to a negative exponent you get the reciprocal. Multiplying something by 1/y³ could be written as a fraction over y³, which D is.
[tex] {z}^{ \frac{1}{2} } [/tex] would be √z, as when you put a value to the power of a fraction, you root it to whatever the denominator is. For example, 9^1/2 = 3 because √9 is 3.
Combining all of these gets you answer D, as it has √z, 1/y³, and x^6.
I hope this helps!
