√ (x y)^3 identity 149052

In the expression, if we replace y with (− y), we will get the identity x 3 − y 3This algebraic identity can be written in the following form too ( a − b) 3 = a 3 − b 3 − 3 a 2 b 3 a b 2 Generally, the a minus b whole cubed algebraic identity is called by the following three ways in mathematics The cube of difference between two terms identity or simply the cube of difference identity The cube of a binomial formula #(xy)^3=(xy)(xy)(xy)# Expand the first two brackets #(xy)(xy)=x^2xyxyy^2# #rArr x^2y^22xy# Multiply the result by the last two brackets #(x^2y^22xy)(xy)=x^3x^2yxy^2y^32x^2y2xy^2# #rArr x^3y^33x^2y3xy^2#

 Seeking a contradiction, we assume that there are matrices X and Y such that XY − YX = I Then we take the trace of both sides and obtain n = tr(I) = tr(XY − YX) = tr(XY) − tr(YX) (by property (1), (2) of the trace) = tr(XY) − tr(YX) (by property (3) of the trace) = 0 Since n is a positive integer, this is a contradictionReplacing y with (−y) in the identity, (xy)3=x33x2y3xy2y3∗) (valid for any elements x , y of a commutative ring), which explains the name "binomial coefficient" Another occurrence of this number is in combinatorics, where it gives the number of ways, disregarding order, that k objects can be chosen from among n objects;
