Sure, let's evaluate the expression [tex]\(\frac{x}{2} + 3z^2\)[/tex] when [tex]\(x = 38\)[/tex] and [tex]\(z = 8\)[/tex].

1. Substitute the values:
- [tex]\(x = 38\)[/tex]
- [tex]\(z = 8\)[/tex]

So the expression becomes:
[tex]\[ \frac{38}{2} + 3 \cdot 8^2 \][/tex]

2. Evaluate the first part:
[tex]\[ \frac{38}{2} = 19 \][/tex]

3. Evaluate the exponent:
[tex]\[ 8^2 = 64 \][/tex]

4. Multiply by 3:
[tex]\[ 3 \cdot 64 = 192 \][/tex]

5. Add the two results together:
[tex]\[ 19 + 192 = 211 \][/tex]

So, the simplified value of the expression [tex]\(\frac{x}{2} + 3z^2\)[/tex] when [tex]\(x = 38\)[/tex] and [tex]\(z = 8\)[/tex] is [tex]\(211\)[/tex].
