b)
$\frac{18}{24} \div \frac{9}{6}$
c)
$\frac{5}{4} \times \frac{4}{5} \times \frac{6}{4} \times \frac{2}{8} \times \frac{8}{3}$
d)
$\sqrt{196} - \sqrt[3]{8} + \sqrt[4]{256}$

Answer 1

Olá amigo

A-)
4-²+ ⅔+ 18 elevado a 0 - 1
4-²+ ⅔ + 1 - 1
1/4² + 2/3
1/16 + 2/3

R: 35/48

B-)
18/24 ÷ 9/6
18/24 × 6/9
2/4

R: 1/2

C-)
5/4 × 4/5 × 6/4 × 2/8 × 8/3
1/4 × 4 × 6/4 × 2/8 × 8/3
6/4 × 2/8 × 8/3
6/4 × 2 × 1/3
2/4 × 2
2/2

R: 1

D-)
$\sqrt{196 } - \sqrt[8]{8} + \sqrt[4]{256}$
$14 - \sqrt[3]{8} + \sqrt[4]{256}$
$14 - 2 + \sqrt[4]{256}$
14-2+4
R: 16

Espero ter ajudado e bons estudos :)
