Please help confirm if I got this problem correctly;

1)2jx(3i-4k)

sol>> 2x3jxi - 2x4jxk

= 6jxi - 8jxk

= 6k - 8i

2) (i-2j)xk

Solutn>> ixk - 2jxk

= -j - 2i

3) (2i-4k)x(ix2j)

solutn>>2ixi Please do help with this ONE

yes, correct.

On the third, break recheck if you typed it right. If the second parenthsis is i x 2j, then the answer is wrong.
