I want to simply $\frac{H^{\xi}\left(\frac{H}{H_0}\right)^{-\xi}}{H_0}$ this term to be $H_0^{\xi-1}$,

I run the code FullSimplify and Cancel but they do not work

Cancel[((H^\[Xi]) ((H/H0)^-\[Xi]) )/H0]
FullSimplify[((H^\[Xi]) ((H/H0)^-\[Xi]) )/H0]

How should I do that?


1 Answer 1

expr = ((H^ξ) ((H/H0)^-ξ))/H0

$\text{H0}^{\xi -1}$
