Explicação passo-a-passo:
[tex](−4)2:−8.+ \sqrt{x} 36.(4−5) \\ ( - 4) \times 2 \div ( - 8) \times \sqrt{x} \times 36 \times ( - 1) \\ - 4 \times 2 \div 8 \times \sqrt{x} \times 36 \times 1 \\ - \frac{4 \times 2} {8} \times \sqrt{x} \times 36 \\ - \frac{2}{2} \times \sqrt{x} \times 36 \\ - \sqrt{x} \times 36 \\ - 36 \sqrt{x} [/tex]
