False

Step-by-step explanation

Given vectors:

a = (3, 4, -2)

b = (2, -7 ,1)

c = (-6, 5, 4)

What to find:

The value of a + c x b

Step-by-step solution:

c x b = (-6, 5, 4) x (2, -7, 1)

c x b = (-12, -35, 4)

a = (3, 4, -2)

Therefore, a + c x b = (3, 4, -2) + (-12, -35, 4)

a + c x b = (-9, -32, 2)

Thus, (-9, -32, 2) ≠ (36, 18, 30)

Hence the answer is False
