\sqrt[n]{x^m}=x^\frac{m}{n}
and \frac{1}{x^m}=x^{-m} so

\frac{8}{ \sqrt[7]{x^{15}} }= \frac{8}{x^ \frac{15}{7} }=8x^{(\frac{-15}{7})}

Steven is solving the equation 3(8−2x)+40=34. He begins with the following two steps.
STatiana [176]

Answer:

<h2>Add 24 and 40</h2>

Step-by-step explanation:

3(8 - 2x) + 40 = 34       <em>use the distributive property a(b + c) = ab+ ac</em>

3(8) + 3(-2x) + 40 = 34

24 - 6x + 40 = 34          <em>combine like terms</em>

-6x + (24 + 40) = 34      <em>Answer: Add 24 and 40</em>

-6x + 64 = 34            <em>subtract 64 from both sides</em>

-6x = -30          <em>divide both sides by (-6)</em>

x = 5
