To evaluate the expression [tex]\(\frac{a}{8} - b\)[/tex] for [tex]\(a = 168\)[/tex] and [tex]\(b = 4\)[/tex], follow these steps:

1. Substitute the given values into the expression:
[tex]\(\frac{168}{8} - 4\)[/tex]

2. Perform the division first, as per the order of operations (PEMDAS/BODMAS):
[tex]\(\frac{168}{8}\)[/tex]

Divide 168 by 8:
[tex]\[ \frac{168}{8} = 21 \][/tex]

3. Subtract [tex]\(b\)[/tex] from the result obtained:
[tex]\[ 21 - 4 \][/tex]

4. Perform the subtraction:
[tex]\[ 21 - 4 = 17 \][/tex]

Therefore, the result of the expression [tex]\(\frac{168}{8} - 4\)[/tex] is [tex]\(\boxed{17.0}\)[/tex].
