( a b c ) 2 = a 2 b 2 c 2 2( ab bc ca ) (1) Given that, a 2 b 2 c 2 = 50 and a b c = 12 We need to find ab bc ca Substitute the values of (a 2 b 2 c 2) and ( a b c ) in the identity (1), we have (12) 2 = 50 2( ab bc ca ) ⇒ 144 = 50 2( ab bc ca ) ⇒ 94 = 2( ab bc ca) ⇒ ab bc ca. Given that Now ,a 3 b 3 c 3 = 3abc ( abc )( a 2 b 2 c 2 ab bc ca ) 3abc = 3abc ( abc )( a 2 b 2 c 2 ab bc ca ) = 0 ∴ a² b² c² ab bc ca = 0 or a b c ≠ 0 Where , a = b = c. ⇒ a 2 b 2 c 2 2 x 23 = 81 ⇒ a 2 b 2 c 2 46 = 81 ⇒ a 2 b 2 c 2 = 81 – 46 = 35 Now, a 3 b 3 c 3 – 3 abc = (a b c) (a 2 b 2 c 2) – (ab bc ca) = 935 23 = 9 x 12= 108 (a) Question 23 Solution Question 24 The product (a b) (a – b) (a 2 – ab b 2) (a 2 ab b 2) is equal to (a) a 6 b 6.

Given a^2 b^2 c^2 = ab bc ca a^2 b^2 c^2 – ab – bc – ca = 0 Multiply both sides with 2, we get 2 ( a^2 b^2 c^2– ab – bc – ca) = 0 2a^2 2b^2 2c^2– 2ab – 2bc – 2ca = 0 (a^2– 2ab b^2) (b^2– 2bc c^2) (c^2– 2ca a^2) = 0 (a –b)^2 (b – c)^2 (c – a)^2= 0.

A^2 b^2 c^2 ab bc ca = 0 eqn (i) (a b)^2 = a^2 2ab b^2 (b c)^2 = b^2 2bc c^2 (c a)^2 = c^2 2ac a^2 adding (a^2 2ab b^2) (b^2 2bc c^2) (c^2 2ac a^2) 2a^2 2ab 2b^2 2bc 2c^2 2ac = 0 so we can divide both sides by 2 and we wind up with eqn (i) so (a b)^2 (b c)^2 (c a)^2 = 0 thus a. A^2 b^2 c^2 ab bc ca > 0, but only for numbers a, b and c that are greater than 0 and not imaginary, but real!. Harsh Gohel , studied at Sardar Vallabhbhai National Institute of Technology, Surat Answered 4 years ago It's given that a^2b^2c^2–abbcac.

Here we will express a^2 b^2 c^2 – ab – bc – ca as sum of squares If a, b, c are real numbers then (a – b)^2, (b – c)^2 and (c – a)^2 are positive as square of every real number is positive So, a^2 b^2 c^2 – ab – bc – ca is always positive. See the proof below If abc=0 Then, a=bc=(bc) Therefore, a^2bc=((bc))^2bc=(bc)^2bc =b^2c^22bcbc =b^2c^2bc b^2ca=b^2c((bc))=b^2c^2bc c^2ab=c^2. 1) Cho a,b,x,y là những số khác 0Biết rằng (a 2 b 2)(x 2 y 2)=(axby) 2 Hãy tìm hệ thức giữa 4 số a,b,x,y 2) Chứng minh các hằng đẳng thức sau a) (21)(2 2 1)(2 4 1)(2 8 1)(2 16 1)=2 321 b) 100 2 103 2 105 2 94 2 =101 2 98 2 96 2 107 2 3) Chứng minh rằng không có các số x;.

Find an answer to your question b2c2abbcca=0 prove that a=b=c tions1 Express the ratio 51 525 ml in the lowest terms1 If 5M = 3N, then M N is4. `∴ a^2 b^2 c^2 ab bc ca >= 0` hence `a^2 b^2 ab bc ca > 0` Hence `a^2 b^2 c^2 ab bc ca` is always nonnegative for all values of a, b and c. A 2 b 2 c 2 – ab – bc – ca = 0 Multiply both sides with 2, we get 2( a 2 b 2 c 2 – ab – bc – ca) = 0 ⇒ 2a 2.

If a^2b^2c^2=abbcca, then, (a^2b^2c^2) (abbcca) = 0, → (a^2 ab) (b^2 bc) (c^2 ca) = 0 → a(a b) b(b c) c(c a) = 0 (1);. A^2 b^2 c^2 ab bc ca > 0, but only for numbers a, b and c that are greater than 0 and not imaginary, but real!.

A^2b^2c^2abbcca&=& 0 \\ 2a^22b^22c^22ab2bc2ca &=& 0 \\ (a^22abb^2)(b^22bcc^2)(c^22aca^2) &=& 0 \\ (ab)^2(bc)^2(ca)^2=0 \end{eqnarray*} So, we have rewritten the equation as a sum of three squares that equals $0$ (Too bad we’re looking for complex and not real solutions!). Ta có a^2 b^2 c^2 = ab ac bc => a^2 b^2 c^2 ab bc ac = 0 => 2(a^2 b^2 c^2 abbcac) = = 0 => 2a^2 2b^2 2c^2 2ab 2bc 2ac = 0.

If a^2b^2c^2=abbcca, find (ca)/b Given a^2b^2c^2abbcca=0 Multiply both sides with 2, we get 2 (a^2 b^2 c^2 – ab – bc – ca) = 0 2a^2 2b^2 2c^2 – 2ab – 2bc – 2ca = 0 (a^2 – 2ab b^2) (b^2 – 2bc c^2) (c^2 – 2ca a^2) = 0 (a –b)^2 (b – c)^2 (c – a)^2 = 0. Given that Now ,a 3 b 3 c 3 = 3abc ( abc )( a 2 b 2 c 2 ab bc ca ) 3abc = 3abc ( abc )( a 2 b 2 c 2 ab bc ca ) = 0 ∴ a² b² c² ab bc ca = 0 or a b c ≠ 0. `∴ a^2 b^2 c^2 ab bc ca >= 0` hence `a^2 b^2 ab bc ca > 0` Hence `a^2 b^2 c^2 ab bc ca` is always nonnegative for all values of a, b and c.
