Question

Use the Fundamental Theorem of Calculus to evaluate the definite integral:
integral 1-2; (1/x^2 - 1/x^3) dx

Answer 1

is this your question?:
\[\huge \int_1^2 (\frac{1}{x^2}-\frac{1}{x^3})dx \]

Answer 2

if yes, then all you need is to rewrite the integrand so you can use the power rule for integrals...
