Question

resolva as expressões numéricas.

se tiver como montar a conta eu agradeço pq precisa de conta.

a) - √-100 - 20 ÷ 2²
b) + 30 ÷ (-√36) + (-18) ÷ 3/1
c) 35 - 6 × 6 + 3/4 ÷ (-9)
d) √49 ÷ (-7) + 2 × (-6) + 11/0
e) √4 + (-75) ÷ (-√25) - 4 × 1
f) (-6)² ÷ (-√16) + 3 × (-3)
​

Answer 1

Resposta:

A-

$- \sqrt{ - 100} - 20 \div {2}^{2}$

$10 - 20 \div {2}^{2}$

$10 - 20 \div 4$

$5$

B-

$+ 30 \div ( - \sqrt{36} ) + ( - 18) \div \frac{3}{1}$

$30 \div ( - 6) - 18 \times \frac{1}{3}$

$- 5 - 6$

$- 11$

C-

$35 - 6 \times 6 + \frac{3}{4} \div ( - 9)$

$35 - 36 - \frac{3}{4} \times \frac{1}{9}$

$- 1 - \frac{1}{4} \times \frac{1}{3}$

$- \frac{13}{12}$

D-

$\sqrt{49} \div ( - 7) + 2 \times ( - 6) + \frac{11}{0}$

$7 \div ( - 7) + 2 \times ( - 6) + \frac{11}{0}$

$- 1 + 2 \times ( - 6) + \frac{11}{0}$

$- 13 + \frac{11}{0}$

$- 143$
