Question

- 1/3 – 2 * 1/4 + (9/8 ÷ 3/4)³=
91/12

61/24

70/48

-101/24

- 25/13

Answer 1

Resposta:

61/24

Explicação passo-a-passo:

- 1/3 – 2 * 1/4 + (9/8 ÷ 3/4)³

-1/3 - 2/4 + (9/8.4/3) ^3

-1/3 - 2/4 + (36/24)^3

-1/3 - 2/4 + ( 46.656/ 13.824)

(-4.608 - 6912 + 46.656)/ 13.824

35.136/ 13.824 = 2,54 equivalente a  61/24

Answer 2

Olá,

$- \frac{1}{3} - 2 \times \frac{1}{4} + ( \frac{9}{8} \div \frac{3}{4} ) ^{3} = \\ \\ - \frac{1}{3} - \frac{2}{4} + ( \frac{9}{8} \times \frac{4}{3} )^{3} = \\ \\ - \frac{ 1}{3} - \frac{2}{4} + (\frac{36}{24} )^{3} = \\ \\ - \frac{1}{3} - \frac{2}{4} + ( \frac{3}{2} )^{3} = \\ \\ - \frac{1}{3} - \frac{2}{4} + \frac{27}{8} = \\ \\ - \frac{8}{24} - \frac{12}{24} + \frac{81}{24} = \\ \\ \frac{61}{24}$
