" 2.If "a=i-2j-3k,b=2i+j-k,c=i+3j-2k," then compute "a*(b times c)

If a = I + 2j - 3k, b = 2i + j + k, c = I + 3j - 2k then (a xx b) xx (b xx c) =

If a=2i-3j+5k, b=3i-4j+5k" and "c=5i-3j-2k then volume of the parallelopiped with coterminus edges a+b, b+c, c+a is _______

I : If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c = 4i + 4j II : If a = i - j + 2k, b = 2i + 3j + k, c = i - k, then magnitude of a + 2b - 3c is sqrt(78)

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

If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c =

If a = i - j + 2k, b = 2i + 3j + k, c = i - k , then magnitude of a + 2b-3c is

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 a = i + j - 2k, b = -i + 2j + k, c = i - 2j + 2k, then a unit vector parallel to a + b + c =
