In mathematics, the cube of sum of two terms is expressed as the cube of binomial x y It is read as x plus y whole cube It is mainly used in mathematics as a formula for expanding cube of sum of any two terms in their terms ( x y) 3 = x 3 y 3 3 x 2 y 3 x y 2Ĺet x^yy^x= (xy)^3=x^3y^33xy (xy) Or,x^yy^x=x^3y^39xy again x=3y so x^3y^39xy= (3y)^3y^39 (3y)y=2727y9y^2y^3y^39y^227=5427y Now we got 54 27y=27, or 27y=27,y=1 Then x=31=2 The values of x& y only satisfy xy=3 and doen't satisfy x^yy^x=27 So there is no solution for the values of x & yThere are two variables and one equation so there will be an infinite number of solutions Let's solve for y xy = xy x = xy y factor out the y x = y (x1) x x − 1 = y so y = x x − 1 x ≠ 1
