prove that if a is a positive integer of the form 6q+5 then it is of the form 3q+2 for same integer q but not conversely
plzzz tell fast for tomorrow's boards
=3p+2 for some pso first part is proved.
now we have to prove that ,
if a positive integer is of the form 3q+2 then it's not of the type 6p+5 for some integer p
but the quantity inside the bracket is not always an integer, hence the answer.
