r^3/(t^2x^10)r3t2x10

Explanation:

There are many different laws of indices. the 2 you need here are:

x^-m = 1/x^m" " and x^m xx x^n = x^(m+n)xm=1xm andxm×xn=xm+n

I like to get rid of any negative indices first.

(r^3color(blue)( t^-1)color(red)(x^-5))/(tx^5) = (r^3)/(color(blue)t*tx^5color(red)(x^5))r3t1x5tx5=r3ttx5x5

=r^3/(t^2x^10)r3t2x10

All the bases are different so there is no further simplifying possible.
