Question on simplifying (for math)

Test Preparation
1

<p>Simplify 4/(x^3/4), no, the answer is no 4x^-3/4.</p>

2

<p>is it 64/x^3 ??</p>

3

<p>Are you asking for:</p>

<p>1) 4/(x^(3/4))? I think the answer is 4x^(1/4)/x. Multiply top and bottom by x^(1/4) to remove the radical from the denominator.</p>

<p>or</p>

<p>2) 4/((x^3)/4)? The answer is 16/(x^3).</p>
