Question

Resolva as expressões numéricas abaixo:
a) √216 3 + 3 . 12 ÷ 4 = b) 670 – 1 x 23 =
c) (78 + 12) ÷ 30 + 10 = d) (44 − 18) ÷ 2 × 17=

Answer 1

Resposta:

A) $=163\sqrt{2}+78$

B) $=-x^{23}+670$

C) $=13$

D) $=221$

Explicação passo a passo:

A) $\sqrt{2}\cdot \:163+\frac{312}{4}$

$=163\sqrt{2}+78$

B) $670-1\cdot \:x^{23}$

$=670-x^{23}$

$=-x^{23}+670$

C) $\left(78+12\right)\div \:30+10$

$=90\div \:30+10$

$=3+10$

$=13$

D) $\left(44-18\right)\div \:2\times \:17$

$=26\div \:2\times \:17$

$=221$
