Question 877115
I would try to help, but first you need to show the expression unmistakably.  Your written expression renders as {{{25^1/2 * 25^1/4}}}.


Expression was later reported as {{{25^(1/2)25^(1/4)}}}.
Simplification:
{{{(5^2)^(1/2)(5^2)^(1/4)}}}
{{{5^(2/2)5^(2/4)}}}
{{{5^1*5^(1/2)}}}
{{{highlight(5*sqrt(5))}}}


(The rendering might fail to show all parts of some characters.  Click on View Source to see the text more clearly; just be aware, you would see only unrendered text).
