Answer (1 of 15) Mentally examine the expansion of (xyz)^3 and realize that each term of the expansion must be of degree three and that because xyz is cyclic all possible such terms must appear Those types of terms can be represented by x^3, x^2y and xyz If x^3 appears, so must y^3 and z^3 (xy) 3 expanded has 4 terms, 1 more than the exponent, x 3 x 2 y xy 2 and y 3 x is decreasing from 3 to 0 from left to right, as y increases from 0 to 3 Any number or variable to the 0 power is 1 Then you need the coefficients for each of the 4 terms You can read that off Pascal's triangle 1 11 121 1331 1, 3, 3 and 1 are the coefficients that go with each of the 4 terms to get Welcome to Sarthaks eConnect A unique platform where students can interact with teachers/experts/students to get solutions to their queries Students (upto class 102) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (MainsAdvance) and NEET can ask questions from any subject and get quick answers by
