Explicación paso a paso:
a: [tex]3x^{2}y[/tex] [tex]-2 xy^{2}[/tex]
3 - [tex]2^{2}[/tex] × 3 - 23²
3 - 4 × 3 - 2 - 529
3 - 12 - 2 - 529
- 540
b: [tex]-\frac{1}{2} x^{3} y^{2} + 3x^{2}z^{2}[/tex]
[tex]-\frac{1}{2}[/tex] - 2³ × 3² + 3 - 2² ×4
[tex]-\frac{1}{2}[/tex] - 8 × 9 + 3 - ( 2 × 4)
[tex]-\frac{1}{2}[/tex] - 72 + 3 - 8²
[tex]- \frac{1}{2}[/tex] - 72 + 3 - 64
[tex]-\frac{1}{2}[/tex] - 133
