Answer 1

Răspuns:

Explicație pas cu pas:

a) 2⁴ x 2³ x 2 = 2 ⁽ ⁴⁺³⁺¹ ⁾ = 2⁸

b)  ( 4/5)³ x ( 4/5)² x (4/5)⁻⁷ = ( 4/5) ⁽ ³⁺²⁻⁷ ⁾ = ( 4/5)⁻² = ( 5/4)²

c) ( - 3,5)⁴ x ( - 3,5)² x ( - 3,5)⁻³ = ( - 3,5 )⁽⁴⁺²⁻³⁾ = ( - 3,5)³

d)  { [ ( 2/3)²]³}⁴ = ( 2/3)⁽²ˣ³ˣ⁴⁾ = ( 2/3)²⁴

e)   [ (3/5)⁻⁷]⁵ = ( 3/5)⁻³⁵ = ( 5/3)³⁵
