$\displaystyle (x+4)^{\frac{1}{5}}-(x+4)^{\frac{6}{5}}$

$\displaystyle

=(x+4)^{\frac{1}{5}}(1-(x+4)^6)

Take out the common factor which is $\displaystyle (x+4)^{\frac{1}{5}} . $

so the first part of the equation reduces to 1 and the second part has a power of 6 ( Note that $\displaystyle \frac{1}{5}\times6=\frac{6}{5}$) - Feb 2nd 2009, 07:23 PMxxabbasxx
