Question to simplify(a 2b 2) 3 (b 2c 2) 3 (c 2a 2) 3 / (ab) 3 (bc) 3 (ca) 3 Answer Let's solve the numerator first if abc = 0 Then a 3 b 3 c 3 = 3abc Now,(a 2b 2) 3 (b 2c 2) 3 (c 2a 2) 3 = a 2b 2 b 2c 2 c 2a 2 = 0 That means we can use this formula here because abc is coming out to be zeroHowever, there is a problem when trying to prove (abc)^2 ≤ 3(abbcca), because, in fact, the opposite is true (abc)^2 ≥ 3(abbcca) You can see that if you expand (abc)^2, simplify, multiply by 2, and use the trivial inequalityX^3y^3z^3 = (xyz)(x^2y^2z^2xy xz yz) 3xyz is a identity/ You may prove by simple foiling for x = a^(1/3) and y = b^(1/3) and z = c^(1/3) you get
3a^3 = 3a^3, a true equation Thus, a = b = c is always a solution, and abc = 3a = 3b = 3c Also, c = a b is a solution a^3 b^3 (a b)^3 = a^3 b^3 a^3 3a^2*b 3a*b^2 b^3 =3a^2*b 3a*b^2 =a*(3ab) b*(3ab) = 3ab * (a b) = 3abc Then abc = ab(ab) = 0Then take c=a and also sheres on ca(abc)^3a^3b^3c^3 =k(ab)(bc)(ca) K is unknown, so find her If a=1,b=1,c=0》(110)^31^31^30=k (11)(10)(01) =k*2 K=3 (abc)^3a^3b^3c^3 =3 (ab)(bc)(ca) October 29, 15 at 841 PM Unknown said See this one((ab)c)^3a^3b^3c^3The formula is (xy)^3 = x^3 3x^2y 3xy^2 y^3 Expand (ab)^3 = a^3 3a^2b 3ab^2 b^3 Expand (bc)^3 = b^3 3b^2c 3bc^2 c^3 Expand (ca)^3 = c^3 3c^2a 3ca^2 a^3 = c^3

For example, we can write $(ABC)' \equiv \big(A (BC)\big)' \equiv \big(A' \cdot (BC)'\big) \equiv A'\cdot (B'C') \equiv A'B'C'$ Indeed, provided we have a negated series of multiple variables all connected by the SAME connective (all and'ed or all or'ed), we can generalize DeMorgan's to even more than three variables, again, due to theChứng minh rằng (abc)^3 = a^3 b^3 c^3 3(a b)(b c)(c a) với mọi a, b, c bằng 3 cách Cách số 1 Khai triển vế trái thành vế phảiExample 1 Solve (4p 5q 3r) 2 Solution This proceeds as Given polynomial (4p 5q 3r) 2 represents identity first ie (a b c) 2 Where a = 4p, b = 5q and c = 3r Now apply values of a, b and c on the identity ie (a b c) 2 = a 2 b 2 c 2 2ab 2bc 2ca and we get (4p 5q 3r) 2 = (4p) 2 (5q) 2 (3r) 2 2(4p)(5q) 2(5q)(3r) 2(3r)(4p) Expand the exponential forms
