Question 855079
<pre>
{{{y=ab^(cx)}}}{{{""=""}}}{{{a(b^c)^x)}}}{{{""=""}}}

We use the identity  {{{z=e^(ln(z))}}} to rewrite {{{b^c}}}

{{{matrix(2,7,

"", "",  "", "", "", "", "",
a(b^c)^x,""="",  a(e^ln(b^c))^x,""="",a(e^(c*ln(b)))^x,"=",ae^(c*ln(b) *x)        )}}}{{{""=""}}}

let {{{d=c*ln(b)}}}, and the above becomes:

{{{y=ae^(d*x)}}}
