Explicație pas cu pas:
a) (2⁴)⁷ - 2²⁸ = 2⁴ˣ⁷ - 2²⁸ = 2²⁸-2²⁸ = 0
b) (3⁵)⁴ : 3¹⁹ = 3⁵ˣ⁴ : 3¹⁹ = 3²⁰:3¹⁹ = 3²⁰⁻¹⁹ = 3
c) (5⁸)⁷ : (5⁵³·5) = 5⁸ˣ⁷ : 5⁵³⁺¹ = 5⁵⁶ : 5⁵⁴ = 5⁵⁶⁻⁵⁴ = 5² = 25
d) (7⁷)⁷ :(7⁷⁷:7⁷ˣ⁵) = 7⁷ˣ⁷ : (7⁷⁷⁻³⁵) = 7⁴⁹ : 7⁴² = 7⁴⁹⁻⁴² = 7⁷
e) (13⁸)¹³ : (13²⁶)⁴ = 13⁸ˣ¹³ : 13²⁶ˣ⁴ = 13¹⁰⁴ : 13¹⁰⁴ = 13¹⁰⁴⁻¹⁰⁴ = 13⁰ = 1
f) 7^¹³^² : (7⁴²)⁴ = 7¹⁶⁹:7⁴²ˣ⁴ = 7¹⁶⁹⁻¹⁶⁸ = 7
g) 2^⁷^² : (2⁸)⁶ = 2⁷ˣ⁷ : 2⁸ˣ⁶ = 2⁴⁹:2⁴⁸ = 2⁴⁹⁻⁴⁸ = 2
h) 3^⁸^² : 3^⁴^³ = 3⁸ˣ⁸ : 3⁴ˣ⁴ˣ⁴ = 3⁶⁴ : 3⁶⁴ = 3⁶⁴⁻⁶⁴ = 3⁰ = 1
