Question 872108
<pre>

{{{expr(7/6)*ln(z-9)}}}{{{""+""}}}{{{ln(z)}}}

{{{matrix(2,1,"",

ln(z-9)^(7/6))}}}{{{matrix(2,1,"",""+"")}}}{{{matrix(2,1,"",ln(z))}}}

{{{matrix(2,1,"",

ln((z-9)^(7/6)*z))}}}

You can leave it like that, or this

{{{matrix(2,1,"",

ln(z(z-9)^(7/6)))}}}

Or you can change to a radical:

{{{ln(z*root(6,(z-9)^7)))}}}

and simplify:

{{{ln(z*root(6,(z-9)^6*(z-9)^1)))}}}

{{{ln(z*root(6,(z-9)^6)*root(6,(z-9)^1))}}}

{{{ln(z*(z-9)*root(6,z-9))}}}
