expand r(2,2,-1)*s(1,-2,3)

expand

r (2, 2, - 1) \cdot s (1, - 2, 3)

2 rs, 2, 1, - 2 rs, 2, 2, 3 - 1 \cdot 1 \cdot rs, 1 \cdot 2, 3

Solution steps

r (2, 2, - 1) s (1, - 2, 3)

= (2 \cdot 2,, - 1) (1, - 2 \cdot 3,) rs

Expand

(2, 2, - 1) (1, - 2, 3) : 2, 2, 1, - 2, 2, 2, 3 - 1 \cdot 1, 1 \cdot 2, 3

= rs (2, 2, 1, - 2, 2, 2, 3 - 1 \cdot 1, 1 \cdot 2, 3)

Expand

rs (2, 2, 1, - 2, 2, 2, 3 - 1 \cdot 1, 1 \cdot 2, 3) : 2 rs, 2, 1, - 2 rs, 2, 2, 3 - 1 \cdot 1 \cdot rs, 1 \cdot 2, 3

= 2 rs, 2, 1, - 2 rs, 2, 2, 3 - 1 \cdot 1 \cdot rs, 1 \cdot 2, 3
