Answer 1

Răspuns:

0,4=(4/10)⁽²=2/5

0,0(6)=(6/90)⁽⁶=1/15

1,(3)=(13-1)/9=(12/9)⁽³=4/3

(³⁾2/5-1/15)²:4/3=(6/15-1/15)²·3/4=(5/15)²·3/4=(1/3)²·3/4=1/9·3/4=1/12

_________________

f=9/32·[(5·3+2)/3-4/21:4/7]

f=9/32·(17/3-4/21·7/4)

f=9/32·(17/3-1/3)

f=9/32·16/3

f=(144/96)⁽⁴⁸

f=3/2

15/10=3/2

15·2=10·3=>30=30 → echivalente
