**1)**in my exams there were 3 simple questions on integration carrying 5 marks each, i solved them correctly but the only mistake i did was at the end of each step i didnt write "+c"

like for example the final step of an integration problem is suppose say:

x

^{2}+9x

^{2}

__+c__

so how much marks i will loose out of 5 for not writing that +c

**2)**and for another question i wrote √50 instead of writing 5√2 as the answer, is that ok or i will loose marks for the same, meaning can 5√2 be also written as √50
