Question 1066217
Write the expression like this in pure text:
(x^(-3)+x^(-2))/x


If put inside of the triple curly brackets tags,
{{{(x^(-3)+x^(-2))/x}}}


Same as, because of the negative exponents,
{{{(1/x^3+1/x^2)/x}}}


Simplest common denominator between numerator and denominator is  x^3.  Multiply the entire rational expression by {{{x^3/x^3}}}.


{{{((1/x^3+1/x^2)/x)(x^3/x^3)}}}

now keep going until finished simplifying.
