Question

Calcule ( não consegui digitar tudo)

Answer 1

A

$\sqrt{49} + \sqrt{81}$

$7 + 9$

$16$

B

$\sqrt[3]{64} - \sqrt[3]{ - 1}$

$4 - ( - 1)$

$4 + 1$

$5$

C

$\sqrt{4} - \sqrt[3]{27} + \sqrt[4]{16} - \sqrt[5]{ - 1}$

$2 - 3 + 2 - ( - 1)$

$- 1 + 2 + 1$

$1 + 1$

$2$

D

$3 \sqrt{25} + 2 \sqrt{4} - 5 \sqrt[3]{8}$

$3 \times 5 + 2 \times 2 - 5 \times 2$

$15 + 4 - 10$

$19 - 10$

$9$

Answer 2

$\sqrt{49}\:+\sqrt{81}=16\\\\\sqrt[3]{64}\:-\sqrt[3]{-1}\:=5\\\\\sqrt{4}\:-\sqrt[3]{27}\:+\sqrt[4]{16}\:-\sqrt[5]{-1}=2\\\\3\sqrt{25}+2\sqrt{4}\:\:-5\sqrt[3]{8}\:=9$

Bons estudos!!
