Oh, okay. This makes a lot more sense nowas i cant type the radical sign the qn seems awkward.
in fact its not 3*sqrt(x+y), the three is on the left of sqrt on the sqrt sign.
I agree - are you sure that the original question didn't read c^6 instead of c^8?truplayer256 wrote:Oh, okay. This makes a lot more sense nowas i cant type the radical sign the qn seems awkward.

So the question is really:
cubic root of (x+y)= c^8
All we do here is take the cube of both sides:
x+y=(c^8)^(3)=c^24... It still doesn't match the OA. Why's this?
