Answer 1

Resposta:

D)24,53,45,39

Explicação passo-a-passo:

a)

$3 {}^{3} - \sqrt{169} + 15 - 8 - 7 {}^{1} + \sqrt{100}$

$27 - \sqrt{169} + 15 - 8 - 7 {}^{1} + \sqrt{100}$

$27 - 13 + 15 - 8 - 7 {}^{1} + \sqrt{100}$

$27 - 13 + 15 - 8 - 7 + \sqrt{100}$

$27 - 13 + 15 - 8 - 7 + 10$

$24$

b)

$15 \times \sqrt{9} - 5 + 4 {}^{2} + \sqrt[3]{27} - 1 - 5$

$15 \times 3 - 5 + 4 {}^{2} + \sqrt[3]{27} - 1 - 5$

$15 \times 3 - 5 + 16 + \sqrt[3]{27} - 1 - 5$

$15 \times 3 - 5 + 16 + 3 - 1 - 5$

$45 - 5 + 16 + 3 - 1 - 5$

$53$

c)

$95 - (6 {}^{2} \div 2 {}^{2} - 1 {}^{0} + (12 \times \sqrt{16} ))$

$95 - (3 {}^{2} - 1 {}^{0} + (12 \sqrt{16} ))$

$95 - (3 {}^{2} - 1 + (12 \sqrt{16} ))$

$95 - (3 {}^{2} - 1 + (12 \times 4))$

$95 - (9 - 1 + (12 \times 4))$

$95 - (9 - 1 + 48)$

$95 - 56$

$39$

d)

$32 + ( \sqrt{4} \times \sqrt{25} - (20 \div 4) + 2 {}^{3} )$

$32 + (2 \sqrt{25} - (20 \div 4) + 2 {}^{3} )$

$32 + (2 \times 5 - (20 \div 4) + 2 {}^{3} )$

$32 + (2 \times 5 - 5 + 2 {}^{3} )$

$32 + (2 \times 5 - 5 + 8$

$32 + (10 - 5 + 8)$

$32 + 13$

$45$
