You can put this solution on YOUR website!
Is this expression
+%28+%2854%2F2%29%2Ax%5E4+%29%5E%281%2F3%29+ ?
-------------------------------
You need the general rule:
+%28+a%5Eb+%29%5Ec+=+a%5E%28+b%2Ac+%29+
The you have the extra step:
+%28+d%2A%28+a%5Eb+%29%29%5Ec+=+d%5Ec+%2A+a%5E%28+b%2Ac%29+
----------------------------------------
That's assuming I'm reading the expression right
+%28+%2854%2F2%29%2Ax%5E4+%29%5E%281%2F3%29+
++27%5E%281%2F3%29+%2A+x%5E%284%2F3%29+
+3x%5E%284%2F3%29+
--------------------------------------
If I read it wrong and the expression is:
+%28+%2854%2F%282x%29%29%5E4+%29%5E%281%2F3%29+
+%28%28+27%2Fx+%29%5E4%29%5E%28+1%2F3+%29+
+%28+27%2Fx+%29%5E%284%2F3%29+
+%28%28+27%2Fx+%29%5E%281%2F3%29%29%5E4+
+%28+3%2F%28x%5E%281%2F3%29%29%29%5E4+
+81%2F%28+x%5E%284%2F3%29%29+
+81%2Ax%5E%28+-4%2F3+%29+
