The answer is --> (1 + 3x)^4 (1 + 18x)

@Alpha: Yeah but I cant seem to understand how do we end up with (1 + 18x)  :-\

Yes, I did with the product rule. I took 3x5 instead of 3x5 + 1 (which was a mistake I made). Isn't the answer 18x5 + 1 correct ?

^ Okay, people don't KILL me ::)

I posted the question in a wrong way.
The question was: x(1 + 3x)^5 and not x(1 + 3x^5)  :-[

Sorry O_O, I got the answer By the way.

Thanks

Alpha:

Aww, you are just so sweet that's why :D. I am not sure about anse :P*He will surely kill me now* ::)

Okay, I have another question

If we have something like (attached) and then we are supposed to take 3(2x + 1) ^(-0.5) as common then shouldnt the remaining be [x + (2x + 1)^-1]
 :-\
