Explicație pas cu pas:

A = [ ( - 3)² x ( - 3 )¹⁰ : ( - 3)⁹]³ : ( - 3)⁷

A = [ ( - 3)⁽²⁺¹⁰⁻⁹⁾ ]³ : ( - 3)⁷

A = ( - 3)⁽³ˣ³ ⁻⁷⁾

A = ( - 3)⁹⁻⁷

A = (-3)²

A = 9

B = - 7⁵ x (-7)⁹ : ( - 7)⁸ : ( - 7)⁴

B = ( - 7)⁽⁵⁺⁹⁻⁸⁻⁴⁾

B = ( - 7)²

B = 49

C = [ 2⁷ x ( - 2)¹² : ( - 2)¹⁵] : ( - 2)²

C = [ 2⁽⁷⁺¹²⁾ : ( - 2)¹⁵] : ( - 2)²

C =  (- 2⁽¹⁹⁻¹⁵⁾) : ( -2)²

C = ( -2⁴): ( - 2)²

C = - 2⁽⁴⁻²⁾

C = - 2²

C = - 4

D = [3²⁴ x ( - 3)¹² : ( - 3)²] : ( - 9)¹²

D = ( 3⁽²⁴⁺¹²⁻²⁾) : ( - 3)²ˣ¹²

D = 3³⁴: ( - 3)²⁴   ( -) la putere para = +

D = 3⁽³⁴⁻²⁴⁾

D = 3¹⁰

D = 9⁵

E = [ 2⁴⁵ x ( - 4)⁵] : ( - 8)⁵ : 2⁶

E = [ 2⁴⁵ x ( - 2²ˣ⁵)] : ( - 2³ˣ⁵) : 2⁶

E = ( - 2⁽⁴⁵⁺¹⁰⁾) : ( - 2¹⁵) : 2⁶

E = + 2⁵⁵⁻¹⁵⁻⁶

E = 2³⁴

F = [ 5¹⁰ x ( -25)⁷ : ( -5)²⁰]⁷ : ( - 25)¹⁰

F = [ 5¹⁰x ( - 5²ˣ⁷) : ( -5)²⁰]⁷ : ( - 5)²ˣ¹⁰

F = ( - 5⁽¹⁰⁺¹⁴⁻²⁰⁾)⁷ : ( - 5)²⁰

F = ( - 5)⁴ˣ⁷⁻²⁰

F = ( - 5)⁸= 5⁸
