Question

Me ajudem com essa conta, por favor!

Answer 1

(1/2+1/2+1/2)(1/2)³

(3/2)(1/8)

3/16

Answer 2

Seja $\text{x}=\left(\dfrac{1}{2}+\dfrac{1}{2}+\dfrac{1}{2}\right)\times\left(\dfrac{1}{2}\right)^3$

 

Observe que:

 

$\left(\dfrac{1}{2}+\dfrac{1}{2}+\dfrac{1}{2}\right)=3\cdot\dfrac{1}{2}=\dfrac{3}{2}$

 

E $\left(\dfrac{1}{2}\right)^3=\dfrac{1^3}{2^3}=\dfrac{1}{8}$

 

Logo:

 

$\text{x}=\dfrac{3}{2}\times\dfrac{1}{8}=\dfrac{3}{16}$
