Answer:

OPTION C

Step-by-step explanation:

We have the following rules:

$ \sqrt[a]{x} = x^{\frac{1}{a} $    and

$ x^a . x^b = x^{a + b} $

OPTION A: $ x \sqrt[7]{x} $

= $x . x^{\frac{1}{7} $

= $ x^{1 + \frac{1}{7} $

$ = x^{\frac{8}{7} $ $ \ne x^{\frac{9}{7} $

So, it can be eliminated.

OPTION B: $ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $

= $ \bigg ( \frac{1}{x^{\frac{1}{7}}} \bigg )^9 $

= $ \bigg ( x^ {\frac{-1}{7}} \bigg )^9 $

= $ x^{\frac{-9}{7}} $

So, this option is also eliminated.

OPTION C: $ x . \sqrt[7]{x} $

= $ x . x^{\frac{1}{7}} $

= $ x^{1 + \frac{1}{7}} $

= $ x^{\frac{9}{7}} $

So, OPTION C is the answer.

How do you factor (y^4-x^9) ? <br><br> Thank you
polet [3.4K]
So since you know that x^2-1 is equal to (x-1)(x+1),
you can figure that this factors to
(y^2-x^3)(y^2+x^3)
because you know how the difference of two squares formula, stated on the top line of this answer.
