Question 179574
If you have the expression {{{(a/b)^(-2)}}}, then to make the exponent positive, simply flip the fraction. So {{{(a/b)^(-2)=(b/a)^2}}} 



So in this case, the expression {{{(37xy)^(-6/7)}}} <i>really</i> looks like {{{(37xy/1)^(-6/7)}}}. Now flip the fraction to get {{{(1/(37xy))^(6/7)}}} which will make the exponent positive.


--------------------------------------------

Answer:


So {{{(37xy)^(-6/7)=(1/(37xy))^(6/7)}}} where every variable is nonzero.
