Answer: 3-
Step-by-step explanation:
Answer:
x = 6
7x = 42
Divide both sides by 7
0.0357142857142857
![\sqrt[n]{x^m}=x^\frac{m}{n}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%5Cfrac%7Bm%7D%7Bn%7D%20%20)
so![\frac{8}{ \sqrt[7]{x^{15}} }= \frac{8}{x^ \frac{15}{7} }=8x^{(\frac{-15}{7})}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B%20%5Csqrt%5B7%5D%7Bx%5E%7B15%7D%7D%20%7D%3D%20%5Cfrac%7B8%7D%7Bx%5E%20%5Cfrac%7B15%7D%7B7%7D%20%7D%3D8x%5E%7B%28%5Cfrac%7B-15%7D%7B7%7D%29%7D%20%20)
