Ex 10.2, 6 Find the sum of the vectors ๐ โ = ๐ ฬ โ 2๐ ฬ + ๐ ฬ, ๐ โ = โ2๐ ฬ + 4๐ ฬ + 5๐ and ๐ โ = ๐ ฬ โ 6๐ ฬ โ 7๐ ฬ. ๐ โ = ๐ ฬ โ 2๐ ฬ + ๐ ฬ, ๐ โ = โ2๐ ฬ + 4๐ ฬ + 5๐ ๐ โ = ๐ ฬ โ 6๐ ฬ โ 7๐ ฬ. Now, (๐ โ + ๐ โ + ๐ โ) = (1 โ 2 + 1) ๐ ฬ + (-2 + 4 โ 6) ๐ ฬ + (1 + 5 โ 7) ๐ ฬ = 0๐ ฬ โ 4๐ ฬ โ ๐ ฬ = โ 4๐ ฬ โ ๐ ฬ โด Sum of vectors ๐ โ , ๐ โ and ๐ โ = โ 4๐ ฬ โ ๐ ฬ
