Hello 老师 and buddies,

I would like to ask regarding question no. 4 from the math practice questions. My answer was B because it is asking for distinct prime factors and I thought that answer A should be wrong because 30 has 5 equal prime factors, right?

Which chapter it is?

Charlotte, I think you mean Q5 on Chapter 1, in the future please be more clear about the question. B. 32 has only 1 prime factor - 2 whereas 30 has 2,3,5, totally 3 prime factors

HI Zeyu, where do we find the number properties example questions answer, such as starting EQ2?

HI Zeyu, I think I need help to understand EQ2 and EQ3 under number propertoes, do you still have the step by step guide. I think I am lost in translation esp in EQ2 . We had F(n), F(g) and F(k), what do they represent as the beginning we also had xyz… I am lost…
