Explicație pas cu pas:

( - 5)² x ( - 5)⁴ x ( - 5⁵ ) = ( - 5)⁽ ⁷⁻ᵃ ⁾
5⁽²⁺⁴⁾ x ( - 5⁵) = ( - 5)⁽⁷⁻ᵃ⁾
- 5⁽⁶⁺⁵⁾ = ( - 5)⁽⁷⁻ᵃ⁾
- 5¹¹ = ( - 5)⁽⁷⁻ᵃ⁾ = > 11 = 7 - a => a = 7 - 11 => a = - 4

[ ( -6) x ( - 5)⁴ + ( - 5)⁴] : ( - 5)⁻² = ( - 5)⁶ x ( - 5)ᵃ
( - 5)⁴ x ( - 6 + 1) : ( - 5)⁻² = ( - 5)⁽⁶⁺ᵃ⁾
( - 5)⁴ x ( - 5) : ( - 5)⁻² = ( -5)⁽⁶⁺ᵃ⁾
( - 5)⁽⁴⁺¹⁾ : ( - 5)⁻² = ( -5)⁽⁶⁺ᵃ⁾
( -5)⁵⁻⁽⁻²⁾ = ( - 5)⁽⁶⁺ᵃ⁾
( - 5)⁵⁺² = ( - 5)⁶⁺ᵃ
( - 5)⁷ = ( - 5)⁶⁺ᵃ => 6 + a = 7 => a = 7 - 6 => a = 1
