6. In a class of 40 students, the number of students who study French is 10 more
than the number of students who study
History. If 8 students study both French
and History, how many students study:
i) History ii) French​

31 is prime. and it’s prime factorization is just 31.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
