Answer 1

Răspuns:

4.

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
