3^(-2)/9^(-1)∶9^(1/2)/2^0 =
3^(-2)/9^(-1)*9^(1/2)/2^0= => Korzystamy z wlasnosci poteg
3^(-2)/(3^2)^(-1)*√9/1= =>
3^(-2)/3^(-2)*3= => potegowanie potegi i pierwiastkowanie z 9
1*3=3 => pierwszy ulamek sie skraca i zostaje 1
3^(-2)/9^(-1)∶9^(1/2)/2^0 = 3⁻²/(3²)⁻¹ : (3²)¹/² / 1 = 3⁻²/3⁻² : 3¹ = 3⁰ : 3¹ = 3⁻¹ = 1/3
