In this video I am going to show you that how you can proof a3b3c3=3abc when abc=0It is a special identity of polynomial of class 9thIt often comes inExample Solve 8a 3 27b 3 125c 3 – 90abc Solution This proceeds as Given polynomial (8a 3 27b 3 125c 3 – 90abc) can be written as (2a) 3 (3b) 3 (5c) 3 – 3(2a)(3b)(5c) And this represents identity a 3 b 3 c 3 3abc = (a b c)(a 2 b 2 c 2 ab bc ca) Where a = 2a, b = 3b and c = 5c Now apply values of a, b and c on the LHS of identity ie a 3 b 3 c 3Since B is an empty set, the statement x∈B is false for all x, so (∀x)( x∈Β ⇒ x∈Α ) is also true Thus, B ⊆ Α Since A ⊆ B and B ⊆ Α we have A = B We will use a direct proof here but later we will use another technique to prove this

(a+b+c)^3 formula proof
(a+b+c)^3 formula proof-There do not exist prime numbers a, b,and c such that \a^3 b3 = c3\ Although Fermat's Last Theorem implies this proposition is true, we will use a proof by contradiction to prove this proposition For a proof by contradiction, we assume that there exist prime numbers \(a\), \(b\), and \(c\) such that \(a^3 b^3 = c^3\)If the scalar triple product is equal to zero, then the three vectors a, b, and c are coplanar, since the parallelepiped defined by them would be flat and have no volume If any two vectors in the scalar triple product are equal, then its value is zero

The area of whole square is ${(abc)}^2$ geometrically The whole square is split as three squares and six rectangles So, the area of whole square is equal to the sum of the areas of three squares and six rectanglesThe left hand side proof is tricky but here it is, although it would be much easier to use the right hand side given a^3 b^3 c^3 3abc factor a^3 b^3 using cubic formula (ab)(a^2 ab b^2) c^3 3abc now we add 3ab and subtract 3ab at the same time into (a^2 ab b^2) getSince B is an empty set, the statement x∈B is false for all x, so (∀x)( x∈Β ⇒ x∈Α ) is also true Thus, B ⊆ Α Since A ⊆ B and B ⊆ Α we have A = B We will use a direct proof here but later we will use another technique to prove this

What the rule says is this if have a disjunction in a proof, and you have shown, through a sequence of subproofs, that each of the disjuncts (together with any other premises in the main proof) leads to the same conclusion, then you may derive that conclusion from the disjunction (together with any main premises cited within the subproofs)Math\mathbf B\times\mathbf C/math is a vector purpendicular to the plane formed by math\mathbf B/math and math\mathbf C/math Hence the vector math\mathbf A\times(\mathbf B\times\mathbf C)/math lies in the plane formed by math\mDefinition The longest side of the triangle is called the "hypotenuse", so the formal definition is
