OpenStudy (anonymous):

welcome

OpenStudy (anonymous):

I think it's 2.

OpenStudy (anonymous):

why?

OpenStudy (anonymous):

one for d other for c and the rest

OpenStudy (anonymous):

correct me

OpenStudy (anonymous):

There are 3 d's and one c

OpenStudy (apoorvk):

actually 'c' and 'd' are variables (unless stated otherwise).

OpenStudy (apoorvk):

so in the simplified form of this expression - there will be just 3.

Really? Oh thank you, then you both have been very helpful to me :)
