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

If put inside of the triple curly brackets tags,

Same as, because of the negative exponents,

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

now keep going until finished simplifying.
