Please help confirm if I got this problem correctly;
1)2jx(3i4k)
sol>> 2x3jxi  2x4jxk
= 6jxi  8jxk
= 6k  8i
2) (i2j)xk
Solutn>> ixk  2jxk
= j  2i
3) (2i4k)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.

4k4j+8i
2ix2j=4k
