Question

Responda: a) (1/2+1)^3 b) 1/2^3 +1

Answer 1

Explicação passo-a-passo:

Boa noite, segue a resolução:

a)

$( \frac{1}{2} + 1 {)}^{3}$

$= ( \frac{1}{2} + \frac{2}{2} {)}^{3}$

$= ( \frac{3}{2} {)}^{3}$

$= \frac{ {3}^{3} }{ {2}^{3} }$

$= \frac{27}{8}$

b)

$( \frac{1}{3} {)}^{3} + 1$

$= \frac{1}{ {3}^{3} } + 1$

$= \frac{1}{27} + 1$

$= \frac{1}{27} + \frac{27}{27}$

$= \frac{28}{27}$

Answer 2

a)(1/2+1)^3

m.m.c de 1 e 2 =2

(1+2/2)^3

(3/2)^3

27/8

b)(1/2)^3+1

1/8+1

m.m.c de 1 e 8= 8

1+8/8

9/8
