Consider distributions now. Calculate right from the definition
a. $x^3\delta''(x)$;
b. $x^2\delta''(x)$;
c. $x^2\delta '''(x)$.
The results may be written through $\delta$-function or its derivatives of the smallest possible order.

Mark is completely correct. Chaojie gave a correct answer to b, correct but unfinished to a (he got $2x\delta$ but this is just $0$—see Mark's solution)
