Question 1208448
<br>
{{{8x^(1/3)-4x^(-2/3)}}}
The smallest power of x is -2/3, so factor {{{x^(-2/3)}}} out of both terms.<br>
And both terms have a constant factor of 4, so factor that out also.<br>
{{{(4x^(-2/3))(2x-1)}}}<br>
Then, since the instructions say to express the result using only positive exponents, move the negative exponent from the numerator to the denominator.<br>
ANSWER: {{{(4(2x-1))/(x^(2/3))}}}<br>
