Answer The Formula for x³ y³ z³ can be derived from the formula of x³ y³ z³ 3xyz x³ y³ z³ 3xyz = (x y z) (x² y² z² – xy – yz– zx) In order to find the formula of x³ y³ z³, we need to send 3xyz to the right side of equal signProve that the equation $x^3y^3z^33xyz=1$ defines a surface of revolution and find the analytical equation of its axis of revolution I think that I need to apply What must be subtracted from 4x^42x^36x^22x6 so that the result is exactly divisible by 2x^2x1?

Answer is (xy z)(x^2 y^2 xyz z^2) You can check by multiplying it out Notice that each term is a perfect cube x^3 y^3 = (xy)^3 So we have a sum of cubes, and the factoring formula is a^3 b^3 = (ab)(a^2abb^2) So we use a = xy and b = z to get x^3 y^3 z^3 = (xy)^3 z^3 = ((xy) z)((xy)^2(xy)zz^2) =(xy z)(x^2 y^2 xyz z^2) check by multiplying itThe algebraic identities for class 9 consist of identities of all the algebraic formulas and expressions You must have learned algebra formulas for class 9, which are mathematical rule expressed in symbols but the algebraic identities represent that the equation is true for all the values of the variables For example; $$\underbrace{x^3y^3}z^33xyz = \underbrace{(xy)^33xy(xy)}z^33xyz$$ $$=\underbrace{(xy)^3z^3}\underbrace{3xy(xy)3xyz} $$ $$=\underbrace{\{(xy)z\}}\{(xy)^2(xy)zz^2\}3xy\underbrace{\{(xy)z\}} \left(\text{ using } a^3b^3=(ab)(a^2abb^2)\text{ for the first two terms }\right) =(xyz)\{(xy)^2(xy)zz^2
Let us consider LHS of the equation LHS = x 3 y 3 z 3 – 3xyz LHS = 1 3 2 3 3 3 – 3(1 × 2 × 3) LHS = 1 8 27 – (3 ×6) LHS = 36 – 18In this question, we will partially differentiate u two times to find the value of k Complete stepbystep answer Now, we will use partial differentiation It is denoted by ∂ We are given u = log ( x 3 y 3 z 3 3xyz) So, partially differentiating u with respect to x, we get ∂ u ∂ x = 3 x 2 3yz ( x 3 y 3 z 3 3xyz)(x^3 y^3 z^3) = (x y z)^3 3{(x)(y)(xy) (y)(z)(yz) (z)(x)(zx)} 6(x)(y)(z) Substituting z for (xy) etc , respectively in the second parenthesis, the RHS reduces to 0 9(x)(y)(z) 6(x)(y)(z) = 3(x)(y)(z)
You can put this solution on YOUR website!Solution x = 2x, y = 2y and z = 4z If x y z = 0, then x 3 y 3 z 3 = 3xyz 8x 3 27y 3 64z 3 = 3 (2x) (2y) (4z) = 48xyz After having gone through the stuff given above, we hope that the students would have understood, "x cube plus y cube plus z cube minus 3xyz" Apart from the stuff given in this section, if you need any other Hint Use the expansion formula of $ {(x y)^3} $ Then replace $ y $ with $ y z $ to write it in three variables Then replace $ y $ with $ y z $ to write it in three variables Further expand it using the condition given in the question and simplify it in the terms of the required result
