{[(1/5)^-2*5^3]^-1*(1/5)^-4}^2: ( 2/15)^2 TORNA 9/4

[Ali Q]

Ecco a te, Angelo:

{[(1/5)^(-2)*5^3]^(-1)*(1/5)^(-4)}^2: (2/15)^2 =

= [(5^2*5^3)^(-1)*5^4]^2: (2/15)^2 =

= [(5^5)^(-1)*5^4]^2: (2/15)^2 =

= [5^(-5)*5^4]^2: (2/15)^2 =

= [5^(-1)]^2: (2/15)^2 =

= (1/5)^2: (2/15)^2 =

= (1/5 : 2/15)^2 =

= (1/5 x 15/2)^2 =

= (3/2)^2 = 9/4
