You can put this solution on YOUR website!
+x+=+-%2827%2F125%29%5E%28-4%2F3%29+


+y+=+%28x%29%5E%28-z%29+
+y+=+1%2F%28%28x%29%5E%28z%29%29+

+y1+=+%28x1%29%5E%28m%2Fn%29+ = n root of x1 raised to the power m. So first we get rid of the negative sign:
+x+=+-%2827%2F125%29%5E%28-4%2F3%29+
+x+=+%28-1%29%2F%28%2827%2F125%29%5E%284%2F3%29%29+
now use the m/n exponent information
+x+=+%28-1%29%2F%28%283%2F5%29%5E%284%29%29+
+x+=+%28-1%29%2F%2881%2F625%29+
+x+=+%28-625%29%2F81+
