That's an expression, so the only thing you can do is simplify it, but that already looks simplified.

Answer:
Hello...... here is a solution :

Hello:
the equation of "m" is : y = ax+b
the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )
a = 3/2
the line " n" that passes through (4, - 3) and parallel to line "m" :
when the slope is 3/2 ( same slope )
the equation in slope-intercept form of the line" n" is :
y – (-3)= (3/2)(x – 4)
Answer:
a) 
b)
c) 
Step-by-step explanation:
a) Let <u>a</u>=<2,1,-3>
The magnitude of <u>a</u> is 

The unit vector in the direction of a is

Using the relation
, we have

b) Let a=2i - 3j + 4k



Using the relation
, we have

c) Let us first find the sum of <1, 2, -3> and <2, 4, 1> to get:
<1+2, 2+4, -3+1>=<3, 6, -2>
Let a=<3, 6, -2>
The magnitude is


The unit vector in the direction of <u>a</u> is

Using the relation
, we have
