256= 16×16= 2⁴×2⁴= 2⁸
Deci 1/256=
= 1/2⁸= (1/2)⁸
b)
16= 2⁴; 81= 3⁴
16/81=
= 2⁴/3⁴= (2/3)⁴
c)
125= 5³; 216= 6³
125/216=
= 5³/6³= (5/6)³
Explicație pas cu pas:
Ex.5
64= 32×2= 2⁵×2= 2⁶
1/64= 1/2⁶= (1/2)⁶
b)
32= 2⁵; 243= 3×81= 3×3⁴= 3⁵
32/243= (2/3)⁵
c) 216:3= 3×72= 3×8×9= 3³×2³= (2×3)³= 6³
343= 7•7•7= 7³
343/216= 7³/6³= (7/6)³
