Question

B={0,(3)+(1/3)^2}*1,5.

Answer 1

Explicație pas cu pas:

$B = \Big[0,(3) + \Big( \frac{1}{3} \Big)^2\Big] \cdot 1,5 = \Big( \frac{3}{9} + \frac{1}{9}\Big) \cdot \frac{3}{2} = \frac{4}{9} \cdot \frac{3}{2} = \bf \frac{2}{3}$

Answer 2

B={0,(3)+(1/3)²}×1,5=(3/9+1/9)×15/10=

(4/9)(15/10)=2/5×5/3=2/3
