Answer (1 of 5) (ABBCCA)² = (AB) ²(BC)²(CA)²2(AB)(BC)2(BC)(CA)2(CA)(AB) Hence, (AB)²(BC)²(CA)²2AB²C2ABC²2A²BC (AB)²(BC)²(CA)²2ABC(BCA). = a 2 ab ac ab b 2 bc ac bc c 2 Rearrange the terms and we get = a 2 b 2 c 2 ab ab bc bc ac ac Add like terms and we get = a 2 b 2 c 2 2ab 2bc 2ca Hence, in this way we obtain the identity ie (a b c) 2 = a 2 b 2 c 2 2ab 2bc 2ca Following are the few examples of this identity. Firstly observe the pattern of the numbers whether the three numbers have ^2 as individual power or not Write down the formula of (a 2 b 2 c 2) a 2 b 2 c 2 = (a b c) 2 2 (ab bc ca) Substitute the values of a, b and c in the a 2 b 2 c 2 formula and simplify Make your child.

 AB A'C BC I know it simplifies to A'C BC And I understand why, but I cannot figure out how to perform the simplification through the expression using the boolean algebra identities I was wondering if someone could show me the steps needed to do this Thank you in advance booleanalgebra Share. The area of the ΔABC can be calculated using Heron's formula S = (AB BC AC)/2 = (10 17 21)/2 = 24 cm = √ 24(24 10) (24 17) (24 21) = 84 cm2 Step 5 Similarly, the area of the ΔACD can be calculated using Heron's formula S = (AC CD AD)/2 = (21 13 )/2 = 27 cm. A2 b2 =(a−b)22ab 3 (a b c)2 = a2 b2 c2 2(ab bc ca) 4 (a b) 3= a3 b3 3ab(a b);.

Given that, a 2 b 2 c 2 = 35 and ab bc ca = 23 We need to find a b c Substitute the values of ( a 2 b 2 c 2 ) and ( ab bc ca ) in the identity (1), we have ( a b c ) 2 = 35 2 (23) ⇒ ( a b c ) 2 = 81 ⇒ a b c = `sqrt81` ⇒ a. Recall the formula `(abc)^2 = a^2 b^2 c^2 2(ab bc ca)` Given that `a^2 b^2 c^2 = 250 , ab bc ca = 3 ` Then we have `(abc)^2 = a^2 b^2 c^2 2 (ab bcca)` `(abc)^2 = 250 2(3)` `(abc)^2 = 256` `(abc) =± 16`.
