B)(-6):[(-3/2)³.(10/9-2/15.10/6)]

Answer 1

Resposta:

Explicação passo a passo:

A=166/69

b= -270/72-20/90

Answer 2

a.

(1/4)² + (5/4 : 4/3)

1²/4² + (5/4 . 3/4)

1/16 + (5 . 3)/(4 . 4)

1/16 + 15/16

(1 + 15)/16

16/16

1

b.

(- 6) : [(- 3/2)³ . (10/9 - 2/15 . 10/6)]

Simplifica por 2

(- 6) : [(- 3/2)³ . (10/9 - 1/15 . 10/3)]

Simplifica por 5

(- 6) : [(- 3/2)³ . (10/9 - 1/3 . 2/3)]

(- 6) : [- (3/2)³ . (10/9 - 1/3 . 2/3)]

(- 6) : [- 3³/2³ . (10/9 - (1 . 2)/(3 . 3))]

(- 6) : [- 27/8 . (10/9 - 2/9)]

(- 6) : [- 27/8 . (10 - 2)/9]

(- 6) : [- 27/8 . 8/9]

Simplifica por 8

(- 6) : [- 27 . 1/9]

Simplifica por 9

(- 6) : [- 3]

6 : 3
