non mi esce 12345

[bimbozza]

[math]{ [ (0,2 \cdot 0,\bar{3})^{10}: (0,01)^4][(0,1)^4]^5}:[(0,1)^3]^7
[/math]

[math]0,\bar{3} =\frac{3}{9}=\frac{1}{3} [/math]

0,2=2/10=1/5
0,01=1/100
0,1=1/10

[math]\left\{ [ (1/5 \cdot 1/3)^{10}: (1/100)^4][(1/10)^4]^5 \right\}:[(1/10)^3]^7[/math]

[math]\left\{ \left[ (1/15)^{10} : (1/100)^4 \right]\cdot (1/10)^{20} \right\}:[1/10]^{21}[/math]

prima di continuare, potresti ricontrollare la prima parentesi quadra?

[(0,3*0,3)^10 :(0,01)^4] ecco

hai ragione...a volte son distratta ^.^

[math]{ [ (0,3 \cdot 0,\bar{3})^{10}: (0,01)^4][(0,1)^4]^5}:[(0,1)^3]^7[/math]

0,3 periodico=3/9=1/3
0,3=3/10
0,01=1/100
0,1=1/10

[math]{ [ (3/10\cdot 1/3)^{10}: (1/100)^4][(1/10)^4]^5}:[(1/10)^3]^7[/math]

[math]{ [ (1/10)^{10}: (1/(10^2))^4][1/10]^{20}}:[1/10]^{21}[/math]

[math]{ [ (1/10)^{10}: (1/10)^8][1/10]^{20}}:[1/10]^{21}[/math]

[math]{ [ (1/10)^2][1/10]^{20}}:[1/10]^{21}[/math]

[math][1/10]^{22}:[1/10]^{21}=1/10[/math]

o, se preferisci 1/10=0,1

Non ti preoccupare...Grazie mille ^.^
