1. Barrelracing

$\sqrt[5]{x^4}$ * $\sqrt[5]{x^4}$

2. Jhannybean

Rewrite the square root as a power.

3. Barrelracing

x^5/4?

4. Jhannybean

Remember, $\large \sqrt[n]{x^m} = x^{m/n}$

5. Jhannybean

So in this case, you have n = 5 and m = 4. According to that rule, you can rewrite it as $$x^{4/5}$$

6. Jhannybean

Now you're simply multiplying $$\large x^{4/5} \cdot x^{4/5}$$

7. Jhannybean

Also remember, $$x^m \cdot x^m = x^{m+m}$$

8. Barrelracing

so what is the answer? a)$\sqrt{x}$ b) x^1/3 c)x$\sqrt[5]{x^3}$ d) x16/25

9. Barrelracing
