It is my country! btw that question was the hardest one in the math exam (the least number of students got it right)

[@nicemathproblems]

Wow! Thank you for sharing that - I'm sure I would not have been able to answer it under exam conditions either! 😅

Very difficult question regardless but honestly the hardest part for me was trying to figure out what part b was trying to state. Just weird wording I thought it was trying to get us to find a value of m or something but m is just equal to 3? I still don't know lol.

@iownkazakhstan yes i agree. condition b is saying that it must be true that |a3| = |a5| but it cannot be true that |a1| = |a3| or |a2| = |a4|
