Supplementary Example 1 If ๐ โ = 2๐ ฬ โ 3๐ ฬ + 4๐ ฬ , ๐ โ = ๐ ฬ + 2๐ ฬ โ 3๐ ฬ , ๐ โ = 3๐ ฬ + 4๐ ฬ โ ๐ ฬ, then find ๐ โ.(๐ โ ร ๐ โ) & (๐ โ ร ๐ โ).๐ โ . Is ๐ โ.(๐ โ ร ๐ โ) = (๐ โ ร ๐ โ).๐ โ ? Given, ๐ โ = 2๐ ฬ โ 3๐ ฬ + 4๐ ฬ , ๐ โ = ๐ ฬ + 2๐ ฬ โ 3๐ ฬ , ๐ โ = 3๐ ฬ + 4๐ ฬ โ ๐ ฬ ๐ โ.(๐ โ ร ๐ โ) = [๐ โ" " ๐ โ" " ๐ โ ] = |โ 8(2&โ3&4@1&2&โ3@3&4&โ1)| = 2[(2รโ1)โ(4รโ3) ] โ (โ3) [(1รโ1)โ(3รโ3) ] + 4[(1ร4)โ(3ร2)] = 2 [โ2+12]+3(โ1+9)+4[4โ6] = 2(10) + 3 (8) + 4(โ2) = 20 + 24 โ 8 = 36 Finding (๐ โ ร ๐ โ).๐ โ = ๐ โ.(๐ โ ร ๐ โ) = [๐ โ" " ๐ โ" " ๐ โ ] = |โ 8(3&4&โ1@2&โ3&4@1&2&โ3)| = 3[(โ3รโ3)โ(2ร4) ] โ 4[(2รโ3)โ(1ร4) ] + (โ1)[(2ร2)โ(1รโ3)] = 3[9โ8]โ4(โ6โ4)โ[4+3] = 3(1) โ 4(โ10) โ 7 = 3 + 40 โ 7 = 36 Hence , ๐ โ.(๐ โ ร ๐ โ) = (๐ โ ร ๐ โ).๐ โ
