Answer:

0.58, 0.58, 0.58

Step-by-step explanation:

Given vector, a = (7.9, 7.9, 7.9)

Unit Vector,
\overline{a} = (a)/(|a|)

The magnitude
|a| = \sqrt{(7.9)^(2) + (7.9)^(2) + (7.9)^(2)}


|a| = √(62.41 +62.41 +62.41)


|a| = √(187.23)

|a| = 13.68


\overline{a} = ((7.9, 7.9, 7.9))/(√(187.23))


\overline{a} = (0.58, 0.58, 0.58)

The unit vector is (0.58, 0.58, 0.58)
