If `a=2i+5j-7k ,\ b=-3i+4j+k\ a n d\ c=i-2j-3k ,\ ` compute `( vec axx vec b)xx vec c` and `axx(bxxc)` and verify that these are not equal.

If =2i+5j-7k,b=-3i+4j+k and c=i-2j-3ka=2i+5j-7k,b=-3i+4j+k and c=i-2j-3k compute (vec a xxvec b)xxvec c and a xx(b xx c) and verify that these are not equal.

If vec a= 2 hat i+ 5 hat j- 7 hat k , vec b= -3 hat I + 4 hat j+ hat k and vec c= hat i- 2 hat j - 3 hat k , compute (vec axx vec b)* vec c and vec a* (vec bxx vec c) and verify that these are same.

If vec a = 2i+3j-4k, vec b = i + j +k and vec c = 4i+2j+3k , then |vec a xx (vec b xx vec c)| =

If vec a = 3i -2j + 2k, vec b = 6i-4j-2k and vec c = 3i-2j -4k , then vec a . (vec b xx vec c) is
