expand 3(2i,-4j)+2(-5i,-2j)

expand

3 (2 i, - 4 j) + 2 (- 5 i, - 2 j)

3 \cdot 2 i, - 3 \cdot 4 j - 2 \cdot 5 i, - 2 \cdot 2 j

Solution steps

3 (2 i, - 4 j) + 2 (- 5 i, - 2 j)

Expand

3 (2 i, - 4 j) : 3 \cdot 2 i, - 3 \cdot 4 j

= 3 \cdot 2 i, - 3 \cdot 4 j + 2 (- 5 i, - 2 j)

Expand

2 (- 5 i, - 2 j) : - 2 \cdot 5 i, - 2 \cdot 2 j

= 3 \cdot 2 i, - 3 \cdot 4 j - 2 \cdot 5 i, - 2 \cdot 2 j

- 1^{2} - 2

\frac{- x + 4}{6 ( x + 2 )}

\frac{d ^{2}}{d x ^{2}} ((y) (3 x - 4))

3 x (2 e^{x - 5 y} y - 5 e^{x - 5 y} y^{2})

(2 x - y + 3 z = 10) \cdot (- 3)
