vă rogg urgent!!! (dau coroana!!)

Answer 1

Răspuns:

Explicație pas cu pas:

a) 3⁷•3⁴ = 3⁷⁺⁴ = 3¹¹

b) 2⁶•2⁴•2 = 2⁶⁺⁴⁺¹ = 2¹¹

c) 7⁸•7⁶ = 7⁸⁺⁶ = 7¹⁴

d) 11⁵³•11⁴⁷ = 11⁵³⁺⁴⁷ = 11¹⁰⁰

e)2²×•2³× = 2²ˣ⁺³ˣ = 2⁵ˣ

f) 13⁵a•13⁵b = 13⁵⁺⁵•ab = 13¹⁰ab

f') 13⁵ᵃ•13⁵ᵇ = 13⁵ᵃ⁺⁵ᵇ = 13⁵⁽ᵃ⁺ᵇ⁾

g) 5⁶²•5³⁷•5 = 5⁶²⁺³⁷⁺¹ = 5¹⁰⁰

h) 7¹•7²•7³•.....•7¹⁰⁰ = 7¹⁺²⁺³⁺·····⁺¹⁰⁰ = 7¹⁰¹ˣ⁵⁰ = 7⁵⁰⁵⁰
