3. Almost, remember (ab) is one term not two.

(ab-3)^10 the 6th is

$17010ab^6$

4. Your calculation is correct to begin with you just did a^6b^6 treating it like two different letters even tho its ab is suppose to be one. Look at it this way, whatever it is (abcdef-3)^10 raise the whole abcdef to a power rather then each each letter by itself. Good job tho look at my other post i solved the whole 10 terms for you !!
