Suppose x 1 is one solution and x 2 is another solution, then ax 1 ≡1 ≡ax 2 (mod m) So x 1 ≡x 2 (mod m) We can divide by a, because, from above, a and m are relatively prime, so the cancellation rule applies That is if x 1 is a solution, and x 2 is any other solution, then x 2 is equivalent to x 1, and x 1 is therefore uniqueI'm not very good at implicit differentiation could someone please help me out I need to differentiate x^2xyy^2=3 using implicit differentiation if someone could explain the steps I would be very greatfulSlove the eqation x/2y=08 and 7/xy/2=10 Slove the eqation x/2y=08 and 7/xy/2=10 Books Physics NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless Chemistry NCERT P Bahadur IITJEE Previous Year Narendra Awasthi MS Chauhan Biology NCERT NCERT Exemplar NCERT Fingertips Errorless Vol1 Errorless Vol2
